Understanding the Water Cycle

This video tutorial explains the water cycle, also known as the hydrologic cycle. It begins with the evaporation of water from the ocean, leading to cloud formation through condensation. The video then describes how precipitation returns water to the surface in various forms, such as rain and snow. Once on the ground, water can either evaporate, become groundwater, or contribute to surface runoff. Groundwater may flow into bodies of water or be absorbed by plants, which release it back into the atmosphere through transpiration. The cycle concludes with water returning to the ocean, ready to begin the process anew.

What is an aquifer?

• A body of saturated rock

• A type of plant

• A form of precipitation

• A type of cloud

How does transpiration contribute to the water cycle?

• By creating precipitation

• By absorbing water into the ground

• By forming clouds

• By releasing water vapor from leaves

Which process involves water vapor being released from plant leaves?

• Precipitation

• Evaporation

• Condensation

• Transpiration

What happens to water that is not absorbed by plants?

• It becomes groundwater

• It evaporates

• It becomes surface runoff

• It forms clouds

Where does surface runoff eventually end up?

• In the clouds

• In the soil

• In the ocean

• In the atmosphere
