Understanding the Water Cycle

What is the process called when water turns into vapor?

• Transpiration

• Precipitation

• Condensation

• Evaporation

What happens to water vapor when it cools down?

• Water vapor condenses into liquid water when it cools down.

• Water vapor remains unchanged when it cools down.

• Water vapor freezes into ice when it cools down.

• Water vapor evaporates into gas when it cools down.

What do we call the water that falls from the sky as rain?

• Humidity

• Dew

• Fog

• Precipitation

Can you name the stages of the water cycle?

• Desalination, filtration, evaporation, condensation

• Evaporation, condensation, precipitation, collection

• Sublimation, filtration, irrigation, absorption

• Condensation, freezing, melting, boiling

How does the sun help in the water cycle?

• The sun provides the energy needed for evaporation, which is a key process in the water cycle.

• The sun cools the water, preventing evaporation.

• The sun absorbs all the water in rivers and lakes.

• The sun causes rain to fall directly from the sky.

What is it called when water from plants goes into the air?

• Evaporation

• Condensation

• Precipitation

• Transpiration

Why is the water cycle important for our planet?

• The water cycle creates more ocean water.

• The water cycle is important for regulating climate, supporting ecosystems, and providing fresh water.

• The water cycle prevents all forms of pollution.

• The water cycle is only important for agriculture.

What happens to rainwater after it falls to the ground?

• Rainwater is absorbed by the atmosphere immediately after falling.

• Rainwater either infiltrates the soil, runs off into water bodies, evaporates, or is absorbed by plants.

• Rainwater turns into snow upon hitting the ground.

• Rainwater is stored in underground caves permanently.

How does evaporation affect the temperature of the air?

• Evaporation makes the air warmer.

• Evaporation lowers the temperature of the air.

• Evaporation increases the temperature of the air.

• Evaporation has no effect on the temperature of the air.

What role do clouds play in the water cycle?

• Clouds absorb water from the ground and prevent evaporation.

• Clouds act as barriers that stop water from entering the atmosphere.

• Clouds transport water vapor and release precipitation, playing a crucial role in the water cycle.

• Clouds are formed only during rainfall and have no other function.
