SCI CHP 15 TEST: Ground Water

Front

What is groundwater?

Back

Groundwater is water that is stored beneath the Earth's surface in soil and rock formations, known as aquifers.

Front

What is an aquifer?

Back

An aquifer is a geological formation that can store and transmit groundwater, serving as an underground water reservoir.

Front

What are the three main types of wells?

Back

The three main types of wells are dug wells, driven wells, and drilled wells.

Front

What is a dug well?

Back

A dug well is a type of well that is excavated by hand or with machinery, typically shallow and lined with stones or bricks.

Front

What is a drilled well?

Back

A drilled well is a type of well created by drilling into the ground, often reaching deeper aquifers and providing a more reliable water source.

Front

What is a pumped well?

Back

A pumped well is a type of well that uses a pump to bring groundwater to the surface for use.

Front

What causes land subsidence?

Back

Land subsidence can be caused by the over-extraction of groundwater, leading to a decrease in support for the ground above.

Front

What is a spring?

Back

A spring is a natural source of groundwater that flows to the surface, often forming a stream or pool.

Front

What is the impact of overdrawing aquifers?

Back

Overdrawing aquifers depletes water resources, causes land subsidence, and can harm local ecosystems.

Front

What is the water table?

Back

The water table is the upper surface of the zone of saturation, where the soil or rock is fully saturated with water.
