Explain the difference between confined and unconfined aquifers.

Back

A confined aquifer is sandwiched between two layers of rock, while an unconfined aquifer has a water table that is open to the surface.

Front

What happens to the water table when too many wells are drilled in one area?

Back

The water table may be drawn down, leading to lower groundwater levels.

Front

Why is aquifer water often cleaner than surface water?

Back

Aquifer water is often cleaner because pollutants are filtered through rock and soil as the water moves underground.

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.

How does drought affect groundwater movement?

Back

During drought, groundwater may flow into rivers, streams, or lakes, which can lower the water table.

Front

What role do aquifers play in the water cycle?

Back

Aquifers store groundwater that can be released to surface water bodies, contributing to the water cycle.

What is the significance of recharge areas for aquifers?

Back

Recharge areas are locations where water infiltrates the ground and replenishes aquifers.
