What is a watershed?

Back

A watershed is an area of land where all the water that falls as precipitation drains into a common outlet, such as a river, lake, or ocean.

Front

What percentage of Earth's water is fresh water?

Back

3% of Earth's water is fresh water.

Front

What is the best land use for watershed drainage?

Back

Wetlands are the best land use for watershed drainage as they help absorb excess water and filter pollutants.

Front

Where is most of the Earth's fresh water found?

Back

Most of the Earth's fresh water is found in aquifers, ice caps, and glaciers.

Front

What role do wetlands play in the hydrosphere?

Back

Wetlands act as natural water filters, help control flooding, and provide habitat for wildlife.

Front

What is the difference between surface water and groundwater?

Back

Surface water is found in bodies of water like rivers and lakes, while groundwater is water that is stored underground in aquifers.

Front

How do glaciers contribute to the hydrosphere?

Back

Glaciers store a significant amount of the Earth's fresh water and release it slowly as they melt, contributing to rivers and lakes.

Front

What is the water cycle?

Back

The water cycle is the continuous movement of water on, above, and below the surface of the Earth, involving processes like evaporation, condensation, and precipitation.

Front

What is an aquifer?

Back

An aquifer is a geological formation that can store and transmit water, providing a source of groundwater.
