Water Cycle

Today we will...

Identify the states of water associated with each part of the water cycle

Define the term Water cycle

Identify the parts of the water cycle

Check your understanding as we go

States of Water

 Solids have a fixed volume and shape.

Their particles are tightly packed and
vibrate but, they stay in place.
Examples of Solid water include –
ice, snow, hail, and sleet

 Liquids have a fixed volume but their

shape changes to fit the shape of the
container they are in. Their particles
are close together, they vibrate and
change place. Liquid water –
examples- dew, ocean water, lake
water, mist, and rain.

•Gases have no fixed volume or fixed shape. Their particles are well

separated without order, they vibrate and move freely and quickly from
place to place. Gas–examples–steam, humidity in air and water vapor

Multiple Choice

What state of matter fixed volume but its shape changes to fit the shape of the container it is in?

• Solid

• Gas

• Liquid

• Ice

 The WATER CYCLE describes the continuous

movement of water on and above the surface of the
Earth.

 Water can change states among liquid, gas, and solid

at various stages of the water cycle.

 The water that was here during the time of the

dinosaurs is the same water that is here today.

What is the Water Cycle?

Multiple Choice

What is the water cycle?

• The continuous movement of water on and above the surface of the Earth. 

• The water that was here during the time of the  dinosaurs is the same water that is here today.

• Water can change states among liquid, gas, and solid.

• We need to describe the water we use every day

What is Evaporation?

 Evaporation occurs when the

sun heats up water in rivers,
lakes, puddles, ponds or the
ocean and turns it into vapor
or steam. The water vapor or
steam leaves the river, lake,
puddle, pond or ocean and
goes into the air.

 Plants lose water out of their

leaves and when this water
evaporates it is called
transpiration.

Multiple Choice

Which is a description of Evaporation?

• Water falls back to the earth in the form of rain, hail, sleet or snow.

• Water  vapor in the air gets cold and changes back into liquid, forming clouds. 

• The sun heats up water in rivers, lakes, puddles, ponds or the ocean and turns it into vapor or steam.

• When water falls to the earth as precipitation, and collects in rivers, lakes oceans, puddles, ponds, streams or underground

What is Condensation?

 Water vapor in the air gets cold

and changes back into liquid,
forming clouds. This is called
condensation.

 You see condensation anytime you

have a cold glass of water and on a
hot day, water forms on the outside
of the glass. The water doesn’t leak
through the glass! The water on
the outside of the glass comes from
the air. Water vapor in the warm
air turns back into liquid when it
touches the cold glass.

Multiple Choice

Which is a description of Condensation?

• Water falls back to the earth in the form of rain, hail, sleet or snow.

• Water  vapor in the air gets cold and changes back into liquid, forming clouds. 

• The sun heats up water in rivers, lakes, puddles, ponds or the ocean and turns it into vapor or steam.

• When water falls to the earth as precipitation, and collects in rivers, lakes oceans, puddles, ponds, streams or underground

What is Precipitation?

Precipitation occurs when
so much water has
condensed that the air
cannot hold it anymore. The
clouds get heavy and water
falls back to the earth in the
form of rain, hail, sleet or
snow.

Rain is a liquid form of
precipitation

Hail, sleet, and snow are
solid forms of precipitation

Multiple Choice

Which is a description of Precipitation?

• Water falls back to the earth in the form of rain, hail, sleet or snow.

• Water  vapor in the air gets cold and changes back into liquid, forming clouds. 

• The sun heats up water in rivers, lakes, puddles, ponds or the ocean and turns it into vapor or steam.

• When water falls to the earth as precipitation, and collects in rivers, lakes oceans, puddles, ponds, streams or underground

What is water Collection?
 When water falls to the earth

as precipitation, it collects
before it evaporates- this is
collection.

 It may create a puddle then start

the cycle over again quickly

 It may soak into the soil and

become part of the ground
water and aquifer– be used by
plants then evaporate to start
the cycle over again

 Or it may run downhill and

collect in the oceans, lakes,
rivers or swamps where the cycle
start up again

What is the largest
water collection on

Earth?

Multiple Choice

Which is a description of Collection?

• Water falls back to the earth in the form of rain, hail, sleet or snow.

• Water  vapor in the air gets cold and changes back into liquid, forming clouds. 

• The sun heats up water in rivers, lakes, puddles, ponds or the ocean and turns it into vapor or steam.

• When water falls to the earth as precipitation, and collects in rivers, lakes oceans, puddles, ponds, streams or underground

The Oceans are the largest water

collections on Earth

Because of all of these reasons the ocean

is very important to the water cycle.

Multiple Choice

As time goes by, and water goes through the water cycle again and again, the amount of water on Earth _______.

• Increases

• Decreases

• Stays the same

• Goes up and down

Multiple Choice

 The water cycle begins with ________.

• Condensation

• Evaporation

• Precipitation

• Trick question-the water cycle has no beginning or end

Multiple Choice

Why do water droplets form on your ice cold glass of water?

•   Your glass is leaking 

   

• Evaporation occurred

   

• Precipitation occurred

• Condensation occurred
