The Sun and Water Cycle

How would water vapor cooling and forming clouds impact the water cycle?

• by increasing runoff

• by increasing evaporation

• by increasing precipitation

• by increasing transpiration

How does a decrease in temperature turn water vapor back into a liquid?

• through condensation

• through transpiration

• through precipitation

• through evaporation

How does water in the ocean returns to lakes in the mountains?

• rivers bring water from the oceans to the mountains

• underground water reservoirs bring water from ocean to mountains

• sun evaporates ocean water, which condenses and precipitates over mountains

After a hot sunny day, a plant withers and dries up. Why? The hot sun causes:

• respiration of the plant's water

• preciptation of the plant's water

• transpiration of the plant's water

• condensation of the plant's water

How does an increase in water temperature, caused by the sun's energy, impact the water cycle? It causes:

• evaporation

• precipitation

• condensation

• transpiration

Jamal filled the swimming pool in his backyard. After several weeks he noticed the water level was lower. Why?

• Because the air temperature cooled.

• Nearby plants used the water.

• Precipitation caused runoff in the pool area.

• Thermal energy (sun) caused evaporation.

Heat from the sun increases the speed of which water cycle process?

• condensation

• precipitation

• evaporation

• transpiration

What must occur before clouds can form?

• water vapor must get warmer

• water vapor must lose heat energy

• precipitation must begin to fall

• transpiration must occur from plants

How are water vapor and condensation similar?

• both are cause by a change in heat energy

• both are caused by a temperature increase

• both are caused by a temperature decrease

Which process allows green plants to control the amount of water stores in their leaves?

• photosynthesis

• condensation

• respiration

• transpiration
