Three States of Water

• Water is found in three forms, or states, on Earth - solid,

liquid, and gas
• Ice is water in its solid state
• Ice forms when liquid water hits the freezing point of 32°F
or 0°C.
• When heat is added to ice, it melts and changes to liquid
water.
• Water in gas form is called water vapor. 200
• Water vapor forms when heat is added to liquid water to a
temperature of 212°F or 100°C.

 The Water Cycle
• The water cycle is the
movement of water into
the air as water vapor and
back to Earth’s surface as
precipitation.
• The water on Earth is
constantly changing from
one form to another in a
continuous cycle that
occurs over and over
again.
© Erin Kathryn
• Evaporation is the change
of state from a liquid to a
gas (water vapor).
• Evaporation occurs when
heat is added to a liquid.
• Water vapor is in the air,
but you cannot see it.
• In the water cycle, heat is
added to water (lakes,
oceans, rivers, streams)
from the sun.

• After the water evaporates,
the water vapor is cooled
by the air and condenses.
• Condensation happens
when gas changes to a
liquid. -

• The tiny drops of water

combine together to form
clouds.

© Erin Kathryn
• When the water droplets in
clouds get heavy, they fall
back to Earth as
precipitation.
• Precipitation is any form of
water that falls from clouds
to Earth.
• Rain, snow, sleet, and hail
are all forms of
precipitation.

Types of Precipitation
• Most common form of

rain •
precipitation
When drops of water fall
through air that is above
freezing
• Falls when the

snow •
temperature in a cloud is
below freezing
Water vapor forms ice
crystals called snowflakes
• Rain that freezes as it falls

sleet to Earth

• Forms when drops of rain

hail freeze and strong winds carry

them higher into a cloud

• When precipitation
occurs, not all water
makes it back to
oceans, lakes, streams,
and rivers.
• Some water soaks into
the Earth.
• This process is called
infiltration.

• Some precipitation
flows downhill on
Earth’s surface.
• This water is called
runoff.
• Runoff water flows
toward streams, rivers,
lakes, and oceans.

 Why It Matters…
• All living things need water to survive.
• The water cycle allows water to be recycled over
and over again.
• By going through the different forms of water, it
allows for us to always have water as a natural
resource on Earth.

 Reflection
• Explain what the water cycle is.

• The water cycle is the process of

water changing from one form
to another over and over again.
• The recycling of water on Earth.

© Erin Kathryn
 Reflection
• Does the water cycle have a start
and stopping point?
• No, the water cycle is a cycle that
continues over and over again.
• Some might say that it starts with
evaporation, but all the steps of
the cycle rely on one another.
© Erin Kathryn
 Reflection
• Why is the water cycle
important?
• The water cycle is important
because all living things need
water to survive. The water cycle
ensures that water can be reused
over and over.
