Water Cycle

How is transpiration important to the water cycle?

• It is the evaporation of water from the leaves of plants back into the atmosphere allowing the cycle to continue.

• It results in the deposition of water vapor directly as ice, so water changes states causing the cycle to move to the next phase.

• It allows plants to absorb water through their roots which is then precipitated back into the atmosphere.

• It permits the diffusion of water from the surface to water tables deep underground which restores groundwater supplies.

What would happen if the Sun is removed from the water cycle?

• The water cycle would not include precipitation but would continue with groundwater flow.

• The water cycle would no longer occur because the Sun provides the energy for evaporation and transpiration.

• The water cycle would no longer occur because the Sun provides energy for the formation of clouds.

• The water cycle would not include evaporation and transpiration but would continue with condensation.

How do transpiration and evaporation compare?

• During both processes, liquid water changes to water vapor.

• During both processes, water vapor changes to liquid water.

• During transpiration, liquid water changes to water vapor, and during evaporation, water vapor changes to liquid water.

• During transpiration, water vapor changes to liquid water, and during evaporation, liquid water changes to water vapor.
