The Water Cycle

Front

What is the water cycle?

Back

The water cycle is the continuous process by which water moves from the Earth's surface to the atmosphere and back, involving processes like evaporation, condensation, and precipitation.

Front

Define transpiration.

Back

Transpiration is the process by which water vapor is released from plants into the atmosphere.

Front

What is precipitation?

Back

Precipitation is any form of water that falls from clouds to Earth’s surface, including rain, snow, sleet, and hail.

Front

What energy source drives the water cycle?

Back

The sun is the primary energy source that drives the water cycle.

Front

Define evaporation.

Back

Evaporation is the process by which liquid water changes to water vapor.

Front

What is condensation?

Back

Condensation is the process by which water vapor in the air cools and changes back into liquid water.

Front

Define groundwater.

Back

Groundwater is water that moves through soil or rock underground.

Front

What is surface runoff?

Back

Surface runoff is the movement of liquid water that flows downhill on Earth’s surface, often after precipitation.

Front

What role does gravity play in the water cycle?

Back

Gravity helps to move water from higher elevations to lower elevations, influencing surface runoff and the flow of rivers.

Front

What is the difference between evaporation and transpiration?

Back

Evaporation is the process of water turning into vapor from surfaces like lakes and rivers, while transpiration is the release of water vapor from plants.
