Answer Type Questions
Question 1.
Name and describe briefly methods of extraction.
Answer:
Mining, drilling, and quarrying are methods of extraction. Mining is a process of
extraction of taking out minerals from rocks under the earth’s surface.

1. Opencast mining: In this, minerals lying at shallow depths are taken out by removing the
surface layer.
2. Shaft mining: In this, deep bores (called shafts) are made to reach mineral deposits lying
at large depths.
3. Drilling: In this, deep wells are bored to take out minerals.
4. Quarrying: It is the process of extraction in which minerals lying very close to the surface
are extracted just by digging them out.

Question 2.
Where are minerals found?
Answer:
Minerals are found in different types of rocks. Metallic minerals are usually found in
igneous and metamorphic rocks that form large plateaus. Examples: iron ore is found in
north Sweden, copper, and nickel in Canada. In igneous and metamorphic rocks in
South Africa, iron, nickel, chromites, and platinum are found. Non-metallic minerals are
found in sedimentary rock formations. Limestone deposits are found in France. Mineral
fuels such as coal and petroleum are found in sedimentary strata.
Question 3.
Describe the mineral distribution in North America.
Answer:
The mineral deposits in North America are found in three zones: the Canadian region in
the north of the Great Lakes, the Appalachian region, and the Rocky Mountains in the
West. Iron ore, nickel, gold, uranium, and copper are mined in the Canadian Shield
Region, coal in the Appalachian region. Western Cordilleras have vast deposits of
copper, lead, zinc, gold, and silver.

Question 4.
Write common uses of minerals.
Answer:
Minerals are important in many industries. Minerals used in gems are usually very hard.
These are then set in varying styles of jewellery. Iron and copper are metals used in
almost everything. Copper is present in everything from coins to pipes and electricity
wires. Silicon, obtained from the mineral quartz, is the base of the computer industry.
Aluminium, obtained from bauxite ore, and its alloys are used in aeroplanes due to their
lightweight. Aluminium is also used in kitchen cookware.

Question 5.
How is hydroelectricity, produced?
Answer:
Hydroelectricity is produced from the energy possessed by water falling from great
heights. River water is stored in dams. When rainwater or river waterfalls from heights, it
flows over turbine blades placed at the bottom of the dam. The moving blades are
connected to a generator which produces electricity from this energy. This electricity is
called hydroelectricity. The water discharged after its production is used for irrigation.

Class 8 Geography Chapter 3 Mineral and Power Resources Long

Answer Type Questions
Question 1.
Name and describe some non- conventional sources of energy.
Answer:
Non-conventional power sources are those power sources that have come into use
recently due to the depleting conventional resources and growing awareness. Solar
energy, wind energy, geothermal energy, nuclear power, and tidal energy are examples
of non- conventional power sources.

Solar energy is the heat and light energy captured from the sun. Solar cells help to
convert this energy to electricity. Solar energy is used in solar heaters, solar cookers,
solar dryers, etc.
Wind energy is the energy possessed by moving air (wind). Windmills are used to
convert wind energy to electricity. Wind farms having clusters of windmills located in
coastal regions and mountain passes.

Nuclear power is the energy possessed by the nuclei of atoms of naturally occurring
radioactive elements like uranium-, thorium, etc.

Geothermal energy is the heat energy obtained from the inside of the earth. The
temperature inside the earth increases as we go deeper. This heat is used to produce
electricity. It is accessed in the form of hot springs. Tidal energy is the energy generated
from tides. It is harnessed by building dams at narrow openings of the sea.

Biogas is a gaseous fuel obtained from the decomposition of organic waste like dead
plant and animal material or animal dung and kitchen waste. It is an excellent fuel for
cooking and lighting and is environment-friendly.

Question 2.
Write the advantages and dis¬advantages of non-conventional sources of energy.
Answer:
Advantages:

1. Non-conventional sources of energy are usually inexhaustible. They do not pollute the
environment.
2. Nuclear power is emitted in large amounts.
3. Most non-conventional sources of energy cost less.
4. These forms of energy are safe to use and clean.

Disadvantages:

1. Windmills are costly to set up. So using them to harness wind energy is costly, even
though the electricity generated from it is cheap.
2. Setting up windmills disturbs radio and TV broadcasts.
3. Harnessing tidal energy destroys the natural habitats of wildlife.
4. Moreover, tidal energy is difficult to harness.
5. Obtaining nuclear energy from radioactive material generates radioactive waste. It is
expensive too.
6. Biogas, although useful and renew¬able, contributes to the greenhouse effect.
