POST P8 Water Cycle/Groundwater

Front

What is a Confined Aquifer?

Back

A confined aquifer is a water-bearing layer of rock or sediment that is trapped between two layers of less permeable material, preventing water from easily flowing in or out.

Front

What is Excretion in the context of the water cycle?

Back

Excretion is the process by which animals release water into the Earth system through liquid and solid waste.

Front

What force causes water to fall from the sky?

Back

Gravity is the force that causes water to fall from the sky to Earth's surface and to flow downhill.

Front

What is a watershed?

Back

A watershed is an area of land where all the water drains to the same body of water.

Front

What is a negative effect of human activity on groundwater?

Back

Groundwater can get contaminated by substances released on the ground.

Front

What is a Recharge Zone?

Back

A recharge zone is an area where water infiltrates the ground and replenishes an aquifer.

Front

What is Transpiration?

Back

Transpiration is the process by which water is absorbed by plants and then released as vapor through their leaves.

Front

What is the role of Solar Energy in the water cycle?

Back

Solar energy drives the water cycle by providing the heat necessary for evaporation.

Front

What is an Unconfined Aquifer?

Back

An unconfined aquifer is a water-bearing layer that is open to the surface and can receive water directly from precipitation.

Front

What is a Confining Layer?

Back

A confining layer is a layer of rock or sediment that restricts the flow of water into or out of an aquifer.
