Unit 5: Weather- The Water Cycle

The Water Cycle

What is the Water Cycle?

• Water Cycle

• Precipitation

• Evaporation

• Condensation

• Groundwater

• Runoff

Multiple Choice

• 97 %
• 71%
• 30%
• 3%

• lakes

• glaciers

• oceans

• rivers

Water on the Move

• Water Cycle: the moving of water between the Earth's surface & the atmosphere.

• Earth's water is always being recycled.

• Water can come from a lot of places: our bodies, oceans, lakes, plants, and soil.

Water on the Move

• Evaporation: the change from liquid to gas.

• Sunlight heats up water particles near the ocean's surface.

• The water evaporates and becomes water vapor.

What goes Up, Comes Down

• Condensation: the change from gas to liquid.

• The water vapor begins to move together and loses energy.

• As it loses energy, it becomes condenses and turns back into water droplets.

• These water droplets form clouds.

Multiple Choice

Most water evaporates from the ocean's surface.

• True

• False

Multiple Choice

When water is heated and turns into a gas.

• Condensation

• Evaporation

Multiple Choice

When water loses energy, forms water droplets and clouds.

• Condensation

• Evaporation

What goes Up, Comes Down

• Precipitation: is water that falls from clouds to Earth's surface.

• As clouds grow and move with wind/air currents, they get heavy.

• When it gets too heavy, the water falls to the Earth's surface as precipitation.

• This can be rain, snow, hail, or sleet.

Where does the Water Go?

• Some water will be used by animals and plants.

• Some water will return to the ocean and evaporate again

Where does the Water Go?

• Some will soak into the ground and become GROUNDWATER.

• The water in ground will eventually be used and recycled by the water cycle.

Where does the Water Go?

• Some will flow across the Earth's surface as RUNOFF

• Water will flow to the lowest point on land (lakes, streams, rivers, oceans).

• Some water will be stored on glaciers-large, moving pieces of ice.

Multiple Choice

How does the water RETURN to the Earth's Surface?

• Precipitation (rain, snow, sleet, hail)

• Groundwater

• Runoff

• Evaporation

Multiple Choice

When water lands on Earth's surface and flows to the lowest part.

• Precipitation (rain, snow, sleet, hail)

• Groundwater

• Runoff

• Evaporation

Multiple Select

Which are examples of precipitation?

• rain

• snow

• runoff

• sleet

• hail

Multiple Choice

When water soaks and is stored in the ground

• Precipitation (rain, snow, sleet, hail)

• Groundwater

• Runoff

• Evaporation

Multiple Choice

What part of the water cycle is this?

• Precipitation (rain, snow, sleet, hail)

• Groundwater

• Runoff

• Water used by plants and animals

Multiple Choice

Precipitation happens when clouds of water droplets are too ______________.

• cold
• light
• heavy
• hot

Multiple Choice

When water condenses, the water vapor in the air gets ___________ and changes back into liquid.

• cold
• hot
• warm
• solid

Multiple Choice

What is the water cycle?

• the 3 forms of water

• the movement of water on, above, or below the surface of the Earth

• when water melts

• when clouds form
