What is 'Groundwater'?

Groundwater refers to water that is located beneath the surface of the earth, stored in soil and rock formations known as aquifers. This water is an essential component of the hydrological cycle, replenishing rivers, lakes, and wetlands. Groundwater can also be accessed through wells and springs, making it a vital resource for drinking water, irrigation, and various industrial processes.

The significance of groundwater lies in its ability to sustain ecosystems and provide water during dry periods when surface water may be scarce. Understanding the characteristics and behavior of groundwater is crucial for effective water resource management, as it can influence both environmental health and human activities.

The other options describe different types of water: atmospheric water (like clouds and humidity), surface water (found in rivers and lakes), and stored water in artificial reservoirs. However, they do not refer to groundwater, which is specifically the water found beneath the Earth's surface.
