Water Cycle

In order for clouds to form, what must happen first?

• Heat energy from the sun changes water in clouds from a gas to a liquid.

• Light energy from the sun changes water on earth from a gas to a liquid.

• Light energy from the sun changes water in clouds from a liquid to a gas.

• Heat energy from the sun changes water on earth from a liquid into a gas

Which process takes place when liquid water changes into water vapor?

• condensation

• transportation

• evaporation

• accumulation

Rain, sleet, snow, and hail are examples of which process in the water cycle?

• condensation

• evaporation

• percipitation

• transpiration

Which part of the water cycle is occurring when warm, moist air cools and begins forming clouds?

• condensation

• evaporation

• precipitation

• transpiration

Which describes the processes involved in causing rain?

• Warm air moves in below cool air, pushing the cool air up, which causes clouds to form and rain to fall.

• Cool air moves in above warm air, pushing the warm air down, which causes clouds to form and rain to fall.

• As warm air rises, it cools, causing water to condense on dust particles and form clouds. The water eventually falls as rain.

• As cool air rises, it warms, causing water to condense and form clouds. The water molecules eventually fall as rain.

Which would most likely cause more runoff?

• decrease in transpiration

• increase in precipitation

• decrease in precipitation

How do plants contribute to the water cycle?

• Plants cool the air and create condensation.

• Plants warm the air and create precipitation.

• Plants give off water through transpiration.

• Plants give off water in the form of runoff or groundwater.

Which process in the water cycle is directly caused by the heat from the Sun?

• evaporation

• runoff

• condensation

• precipitation

In the water cycle, which must happen directly before condensation?

• evaporation

• precipitation

• transpiration

• runoff

What causes the water to evaporate and change to water vapor?

• condensing

• cooling

• heating

• rising
