Physical Factors
There are many reasons why places are located where they are.
Physical characteristics of the area affect where places are located.
It is important to consider the landforms. Are there hills, ridges, or
valleys? Bodies of water are also important. Is there a lake or a river
nearby? Well-drained soil makes a better location for a place than
soil that is poorly drained where flooding might occur. Vegetation,
weather, and climate also affect where places are located. Is the area
forested, or is it grassland? Is it cold or hot, wet or dry?

Human Factors
Other places were chosen for their location based on human char-
acteristics. People tend to locate where there are other people. Large
cities attract people. If there is a river or lake, communities tend to
spread along the riverbank or the lakeshore. People tend to live with
people of a cultural group similar to their own. Religious reasons can
also affect where people choose to live. Some people want to live
near the centre of their faith, like Jerusalem or Mecca.
Locations for places like towns, farms, or factories are chosen
because of distinctive human and physical characteristics. These dif-
ferent characteristics allow us to distinguish places from each other.

Human Regions
Human regions are defined by human characteristics, such as how
many people live closely packed into a region. Cities are regions with
a high population density. Rural areas are regions with low popula-
tion density. Other ways to form human regions include culture
(language, religion, customs), political boundaries, or time zones.
A region can be defined in more than one way. For example,
the province of Québec has political boundaries, so it is a political
region. It is made up of mainly French-speaking people, so it is also
a cultural region.

Hurricane Increase
In the past decade, more frequent and more intense hurri-
canes and tropical storms have affected North America and
the Caribbean. Many people believe that global warming
and effects like El Niño are to blame. In 2005, Hurricane
Katrina brought great devastation to the Gulf of Mexico
coast in the United States, especially to New Orleans. By
2007, New Orleans still needed more reconstruction despite
the tremendous efforts of governments and citizens.

This is a photograph of
Hurricane Frances, which
struck the coast of Florida

States suffered many storms.

A wide range of road systems exists to accommodate the various
vehicles we use. Roads range from narrow dirt lanes to complex net-

place depends on its nearness to areas of high population, markets,
and other large centres.

Pipe It On Through
Most of us are unaware of how much we rely on pipelines. Every
time you get water from a drinking fountain or flush a toilet, you
use a pipeline. We use pipelines to move water, waste, oil, gas,
chemicals, and coal. Foods such as grains (mixed with a liquid) can
be pumped through pipelines.
Pipelines have several advantages. Materials move continuously
with little labour involved. The movements are direct from point to
point and require little maintenance. The big problem is the cost of
installation.
Large pipelines (up to 120 centimetres in diameter) move oil in
huge quantities. In Canada, our largest pipeline is the Interprovincial

A food web is a complicated feeding relationship between producers, herbivores, carnivores,
and omnivores. Nearly all species feed on more than one type of food. This makes the food web
very complicated. Any toxic (deadly) chemicals eaten by one species will be passed along to the
others. The higher on the food pyramid a species is, the more of these toxic chemicals it eats.
That is why bald eagles and beluga whales are now threatened with birth defects and disease.

A deer stays alert to guard against a predator like
a wolf. What would be a predator of a wolf?
The Balance of Nature
Each ecosystem can support only a limited number
of plants and animals in a close relationship.
A good example of this can be found in wolf-
management plans. If wolves are removed, the deer
population rises. The deer then overeat the local
plants, especially young and low-growing trees.
Soon, even that food source is gone. Weakened by
the lack of food, the deer are more likely to die from
disease, from exposure to cold, or by being eaten
by predators. Some deer might move to another
area with a better food supply. Over time, predators,
disease, and migration reduce the size of the deer
herd. Changes to any part of the system can upset
the delicate balance of nature.
Humans are a huge part of many food webs. There
are so many people on Earth that our needs for food
and other resources have seriously affected many food
webs. The result is that many life species have become
extinct. That is, they no longer exist anywhere on
Earth. As well, many species are endangered, or at
risk of becoming extinct.

Fragile Ecosystems
Ecosystems are constantly changing. As the climate changes, an
ecosystem may get drier and drier. Vegetation that prefers drier
conditions will do well and gradually become dominant. Trees and
plants that need more water will die off. Wildlife that can stand a
drier environment will increase.
Some ecosystems can handle change better than others. Ecosystems
that are drier and cold tend to be more fragile than others. They have
more difficulty handling changes. These ecosystems have fewer species.
When a change occurs, they have fewer choices to fall back on.
The tundra is a good example of a fragile ecosystem. It is both
cold and dry, with a very limited number of species. Suppose a
predator has only two animals on which it feeds. If one of these is
drastically reduced in number, many of the predators will starve.
This kind of change is much less likely in a warm, wet environment,
where there are far more species and very complex food webs.

Conflicting Viewpoints
Not every group of people sees the environment in the same way.
When Europeans entered North America, they placed a value on
furs that First Nations peoples and Inuit would have considered
foolish. First Nations peoples and Inuit used the furs they needed
for survival. The Europeans used the environment for its riches. First
Nations peoples lived with the environment. They used what they
needed, but they did not exhaust the resources.
In North Africa, local peoples lived more or less in balance
with their environment. They grew grains and raised animals. The
Europeans saw a chance to grow cash crops like peanuts. These crops
had high value, but growing them made the soil less fertile and more
easily eroded. Drought affected the soil more easily. The price of
growing cash crops became the environment.

Acid rain has become a major problem in several areas of the world.

Landforms
We live on landforms, which are the natural
physical features of the land. Most humans live
on the flattest or gently rolling areas of Earth.
Our landforms are changing all the time due to
forces on and within Earth.
Volcanoes
Volcanoes are landforms created by magma
escaping from below Earth’s surface. Volcanoes
are erupting regularly and building new land on
our continents and in the oceans. There are over
900 active volcanoes in the world.
Figure 6.8
Located in Hawaii in the United States, Kilauea is the
most active volcano on Earth. It has been erupting
almost continuously for the past 25 years. Check an
atlas or the Map Appendix to find the volcano that
is closest to where you live.
Fold Mountains
Moving plates buckle, bend, and fold rock layers
upward to create fold mountains. When plates
collide, the resulting pressure forces the rock to
bend and rise up.
Figure 6.9
These fold mountains are located in Banff, Alberta. The Canadian Rockies and the Himalayas
in south Asia are fold mountains. Can you see the bending in the rock layers? These mountain
ranges were once relatively flat layers of rock that built up on ancient sea bottoms.
126 U N I T 2 : Patterns in Physical Geography
Plateaus
A plateau region is formed when a fairly flat area in a mountain
region has been uplifted by plate movement. Plateaus are typically
flat high areas with steep sides.
Shields
Shields are the original foundations
for our continents. Other landforms
were built upon them. Major world
shields include the Brazilian Shield,
the Central Massif of France, and the
Canadian Shield.
Figure 6.11
A shield is the base of an ancient
mountain region. The mountains

People may confuse weather with climate. Weather deals only with
short-term changes, while climate is long term. Climate refers to the
yearly patterns of precipitation and temperature that emerge when all
the daily weather patterns are combined.
Geographers look for patterns in the way temperatures and pre-
cipitation change over the year. Geographers study climate because
its patterns tell a great deal about places. Climate is one of the most
important factors influencing the vegetation found in a place.
Together, climate and vegetation shape the soils. The climate, vegeta-
tion, and soils of a place influence people and their activities.
Seasonal Changes
In Ontario, the seasons are spring, summer, fall, and winter. However,
in the north, there are really only two seasons — a long winter and
a short summer. In the tropics, the temperature is fairly constant
throughout the year, but there is a rainy season and a dry season.

Climate Graphs
To describe the climate where you live may seem like a difficult
task, but there is a simple and effective method. Climates can be
studied and compared by analyzing climate graphs. A climate graph
makes it easier to identify patterns because it combines two graphs.
Temperature is displayed using a line graph, and precipitation is
shown using a bar graph.

Soils
The type of soil in an area will help to determine the type of natural
vegetation and how well it grows. Soil contains moisture, air,
and organic material. It also contains vital minerals such as
phosphorous, potassium, and calcium that are necessary
for plant growth. To meet daily requirements,
vegetation relies on the minerals contained in
the soil. Unfortunately, not all soils are really
productive. Desert soils are often sandy and lack
nutrients. The sand is unable to hold water and
lacks organic material.

Drainage
Water drains from the highest point of land in an area to the lowest.
Rivers flow from the high ground to the low. Look at the map in
Figure 8.3. Can you see that rivers can flow downhill in different
directions? Some flow north, while others flow south. The higher land
that divides two different drainage basins and sends one river one way
and the other in a different direction is known as the divide.
The Oak Ridges Moraine, just north of Toronto, divides two
drainage basins. This moraine is the divide between rivers that drain
north to Lake Simcoe and rivers that drain south to Lake Ontario.
The Oak Ridges Moraine was created during the last Ice Age. The
ridge of sandy hills acts as a giant rain barrel for the Greater Toronto
Area. The sand and gravel of the moraine soak up rain and snow,
and allow it to move down into large underground natural reservoirs
called aquifers. Many communities dig wells into these aquifers for
drinking water. Recent development has threatened to destroy this
important physical feature and change the flow of the rivers that Figure 8.3
have their headwaters in the moraine.
The Oak Ridges Moraine is a long
ridge of land stretching from the

Fixing a Damaged River
The Trout River is a small river on Prince Edward
Island. It flows through an area of potato farms, a
crop for which Prince Edward Island is famous. The
red sandy soil of this part of the province is easily
eroded. The Trout River used to be murky with sed-
iment and polluted with pesticides that were used
on the crops. Fish had trouble surviving in the dirty
water. A group of volunteers started the Trout River
Environmental Committee (TREC) in 1993 to try
to save the river. Over the years, TREC gradually ex-
panded its interests. It now covers six watersheds
and over 150 kilometres of fresh water.
The committee’s first action was to stop the
soil from washing into the river. They planted
trees and shrubs along the banks to hold the soil
in place. They worked with local farmers to help
them reduce the amount of soil that washed off
their fields. They also built brush mats — clumps of
evergreen trees tied together — that they fastened
in the river. These brush mats trapped sediments
so that the water ran clear. Adding bird and bat

Drainage Patterns
All the tributaries that feed into the main channel form different
types of patterns called river drainage patterns. The drainage pattern
is affected by the underlying rock — the rock that the river flows
over. Different types of rock erode at different rates. Soft rock (for
example, limestone) erodes more easily and faster than hard rock
(for example, granite).
Dendritic drainage
Dendritic Drainage Pattern pattern
Most rivers have a dendritic drainage pattern.
Imagine a leaf, with all the veins connecting to
the main vein in the centre of the leaf. Think of
the main vein as being the main channel of the
river, and the small veins as being the tributaries.
Tributaries join the main branch of the river in
a V-shaped junction. The V points downstream,
toward the mouth of the river. Dendritic drainage
patterns usually occur in gently sloping areas
where all the underlying rock is about the same
hardness, so that it erodes or wears away in a uni-
form manner. Most of the rivers that drain into
Lake Ontario have a dendritic drainage pattern.
Trellis drainage
Trellis Drainage Pattern pattern
Some rivers have a trellis drainage pattern — a
rectangular pattern where the tributaries flow
perpendicular to the main branch of the river.
These tributaries are very often located where
there are bands or rows of hard rock and soft
rock. Tributaries travel along the areas that erode
faster (softer rock) and break through the hard
rock where they can.

of agriculture are practised in different parts of the world. Three main
types of agriculture are subsistence, commercial, and specialized.
Subsistence Agriculture
In many parts of the world, farms can produce only enough food to
support the farmers and their families. Everything the family produces
goes toward feeding and providing for the household. Nothing is left
over to sell. Farmers usually have to plant a variety of crops to meet
their needs. This type of farming is called subsistence agriculture.
Subsistence farming exists in many developing countries. This is
often because the soil conditions are poor. This type of farming also
occurs in areas with harsh climates.

Tsaatan Nomads
The Tsaatan nomads live in a remote part of northern Mongolia. This
subarctic land of forests, lakes, and mountains is quite similar to some
parts of Western Canada. The people are subsistence herders who
depend on reindeer for their survival. The reindeer (called caribou in
North America) provide most of the raw materials for shelter, food,
and clothing. The Tsaatan live in teepees (similar to those of some of
the early North American First Nations) made from reindeer skins.

Bananas are a plantation crop grown in the coastal lowlands of
Central America, Colombia, Ecuador, Philippines, and throughout
many parts of tropical Africa. Banana plants need hot weather, at
least 120 millimetres of rain per month, and deep rich soil.
Very often, a growing banana bunch is covered in a Bananas are harvested when they

Specialized Agriculture
Specialized agriculture is a term used to refer to crops that are
produced only in certain places. Specialized agriculture is successful
because these crops or livestock require unique conditions that
are found in these locations. Pineapples, for example, require hot
temperatures and can be grown only in tropical countries. Citrus

Rice-Fish Farming
Rice-fish farming has been practised for centuries in China and
other southeast Asian countries. Most varieties of rice are grown
in flooded fields called paddies. The paddies are kept filled with
water for most of the growing season. Small fish are released
into the water and they live there until harvest time. These
fish feed on the weeds and other plants in the paddies that
would otherwise compete with the rice for sunshine, fertil-
izer, and nutrients. The fish droppings add to the fertility of
the soil and increase crop production. When the rice crop is
harvested, so are the fish.

Processing Resources
To understand how resources have
to be processed, trace the steps in
making a pair of jeans. The natural
resource — the cotton — must first
be grown and picked. The cotton
bolls are then trucked to a mill
where the fibres of the boll are
wound together into cotton thread.
Large machines weave the indi-
vidual threads together into a
cotton fabric. The cloth is dyed
blue or black, or whatever colour is
popular, and shipped to a clothing
manufacturer. There, the fabric is
cut into shapes and sewn together
into a pair of jeans. Labels are put
on the jeans, and they are shipped
out to stores.

Advancing Technology
Humans have learned how to process natural resources to better meet
our needs. We use technology as a tool to modify resources. Technology
is the practical use of scientific knowledge to solve problems.
Technology has changed over time. As technology changed, our
use of natural resources also changed. Early humans used only plants
and animals to meet their clothing needs. Modern humans still use
plants and animals, but now we also use other natural resources that
require much processing, such as minerals and chemicals made from
petroleum. The use and processing of resources can affect the natural
environment, as you will learn in this unit.
Modern Technology
• Fabrics and coverings are made
out of human-made materials,
such as nylon and lycra.
• Raw materials include petroleum.

An important fact in our world is that most people want more things.
They want nice cars, trendy clothes, larger homes, more food, a lot
of electronic goods, and so on. The demand is growing for just about
every natural resource. Some experts think that between 2005 and
2055, the total amount of the world’s natural resources that people
consume, or use, will grow by at least 100 percent, and perhaps by
up to 500 percent. Energy consumption will be an important part of
this growth. Experts warn that non-renewable supplies like oil and

Animals as Resources
Humans have always hunted wild animals for food. Domestication,
or the taming of wild animals, started as early as 12 000 years ago.
Then, animals could be used for many more purposes. Dogs protected
people and their animals (for example, sheepherding), while sheep,
goats, and cattle served as easily available food sources. Over time,
other animals were tamed for use as pets and beasts of burden (or
work animals). People used the skins of domestic animals to make
clothing and shelter. Many domestic animals had dual purposes.
Cattle provided milk, and they were also used as draft animals to
help people do their work.

Planar Projection
Earth is projected onto a
flat surface that touches
the globe only at a single
point. A map of this type

Conic Projection
Earth is projected onto a
paper cone placed on top
of the globe. The map will
be the least distorted on
the line where the cone
touches the globe. This is
a common projection used
for portraying Canada.
Cylindrical Projection
Earth is projected onto a
paper cylinder wrapped

projection is most accurate
near the equator, but it is
distorted near the poles.

Temperate forests are located north of the tropic of Cancer and south
of the Tropic of Capricorn. These forests grow in climates that are
cooler and less moist than in the tropical regions. They have growing
conditions that vary considerably. These growing conditions produce
the following different types of forests:
• Deciduous forests have trees with broad leaves that fall in the
autumn (including oak, maple, beech, and hickory). Deciduous
forests occur where it is warmer.
• Coniferous forests have trees that keep their needle-shaped
leaves all year round and bear their seeds in cones. These for-
ests grow where it is cooler. Tree species include pine, spruce,
and fir.
• Mixed forests grow between coniferous and deciduous forests.
These forests have trees from both kinds of forests.

The types of wood products made from logs depend on the types
of trees that are being cut. Deciduous trees found in warmer temperate
locations are hardwoods. This wood is dense and hard. It is useful
for making furniture and flooring. Needle-leafed coniferous trees that
grow in cooler climates are softwoods. Their wood is not as strong as
hardwoods, but the trees grow faster. Canada produces 20 percent of
the world’s total softwood. Most of it comes from British Columbia.

resources because they do not remain in one location. Flow resources
move about because of natural actions in the physical environment.
Humans use flow resources in a variety of ways. In fact, we refer
to flow resources as the global commons. These are resources that are

Solar energy The Sun gives off vast amounts of solar energy. Only a tiny
amount of the total energy produced by the Sun reaches
Earth’s surface.
Winds Earth’s surface is hotter near the equator and colder near
the poles. This creates areas of high air pressure at the poles
and low air pressure at the equator. Winds blow from areas
of high pressure to areas of low pressure.

Surface Irrigation
Most places where irrigation is practised use surface irriga-
tion. In fact, about 96 percent of all irrigation is surface
irrigation. Pipes, canals, and ditches carry water to the fields.
Farmers make small openings in the walls of the pipes to
let the water flow into the canals and ditches and onto the
fields. When the soil is wet, the openings are closed. Some of
the water evaporates when this method is used.
Sprinkler Irrigation
With sprinkler irrigation, the water is carried by pipes to the
field. Then, the water is sprayed onto the crops using a sprin-
kler head, much like how lawns are watered. This system is
used mainly by North American farmers.
Drip Irrigation
In drip irrigation, water pipes run to each plant. Water drips
directly onto the roots. Very little water is wasted with drip
irrigation. Because of the high costs
involved — the cost of labour, the
pipes used, and the high level of
technology needed — this system is
used only in rich countries.

River Diversions
Often, farmers in a region want a lot more water than what they have
to set up irrigation processes. To get the extra water for these farmers,
governments will actually move rivers. The direction and course of a

Québec, the Innu tried to stop an expansion of the Churchill Falls power
project. They argued that the construction would destroy their way of life.
The reservoir would flood their hunting areas and destroy ancestral lands.
The Innu had the following to say about the project:
“Go home! Go home! Let the Innu live!”
“I feel as if it’s my own heart that’s going to be flooded.”
“We demand respect for our territory, our way of life, and our rights.”
The Innu protests, along with other problems, stopped the
expansion project. There still are many who would like to see the
Churchill Falls power project create more wealth for Canadians.

bowhead whales? Why did some
people criticize them for it?
We know little about the oceans’ ecosystems because they are so
complicated. The oceans provide a huge variety of species and con-
ditions. The world’s oceans are so vast that most people believed we
could never affect them. They were very wrong!
Overfishing
With our modern technology, we have become so efficient at catching
fish that we are overfishing the oceans. Some fish species are disap-
pearing. The United Nations has estimated that the most that can be
fished from the oceans is 80 million tonnes of fish per year. If more
than this is harvested, the fish cannot reproduce quickly enough.
They will disappear. We are currently harvesting about 101 million
tonnes of fish a year, which is well over the limit. If this overfishing
continues, fish catches will drop in the future. More people around
the world will go hungry as a direct result.
Canada is already suffering the effects of overfishing. In the
1990s, the amount of cod being fished on the East Coast of Canada
dropped. The government of Canada banned fishing for cod in 1992
because so few fish were left. It was hoped that the ban would allow
the fish to become plentiful again, but that has not happened. Only
a very few cod can now be caught each year. A similar situation is
developing with the salmon stocks on the West Coast.

Note the changes in the amount of cod caught on Canada’s East Coast from 1989 to 2005.
Pollution
Pollution is another threat to the oceans. Pollution reaches the ocean
waters in the following ways:
• through rivers
• from the atmosphere
• from factories and cities along the coasts
• directly from ships
Oil spills from damaged ships pollute the water. Ships often just dump
their sewage and waste oil directly into the ocean. Those parts of the
world with large populations, such as the coasts of Europe and Asia,
are heavily polluted. People and pollution seem to go hand in hand.

D isaster! Your plane has crashed. You and two friends are stranded

you can survive. There is food — nuts, berries, and fish in the sea.
A small stream provides drinking water.
You survive for a few months, but then you begin to think of
ways to use the island’s resources to improve your life. You
discuss your plans with your friends. “Why don’t we cut
down more trees and build a really nice hut? Why not
eat more fish? They’re there just for the taking.”
C H A P T E R 1 4 : Sustainable Development 287
Your friends point out some problems. If you cut down the trees
to build a hut, you will destroy the plants that provide your nuts and
berries. Also, catching too many fish today means that there will be
fewer fish to catch tomorrow. The improvements that you want to
make are going to use up your resources now so you will not have
them in the future.
This is the same dilemma facing the people of the world. How
can we use our resources wisely without using up or polluting our
resources? We need to use resources today in such a way that they

Finding the Main Idea
When you read a long section
of text, begin by identifying
the main idea. The main idea
• usually occurs at the
beginning of the text
• usually captures the whole
point of the text
• often appears in the title
The main idea is always
followed by supporting
ideas, which strengthen
the main idea and can
include facts, examples,
and interesting points.

Travel Wisely
Use a bicycle or public transit whenever possible. By not using auto-
mobiles, you are saving energy and reducing pollution. At the very
least, commuters should use a car pool so only one vehicle is being
used instead of several.
Figure 14.13
Using public transit like streetcars in
Toronto, Ontario, saves energy and
money, too. How often do you take
the bus or subway? How often do
you and your family bike or carpool?
