What is groundwater?

1. Water surface found in lakes

2. Water located beneath the earth's surface

3. Water from rainfall

4. A type of irrigation system

The correct answer is: Water located beneath the earth's surface

Groundwater refers specifically to water that resides beneath the earth's surface, typically stored within the pores and fractures of soil and rock formations, known as aquifers. This underground water is critical for various ecosystems and is also a primary source of drinking water for many communities through wells and natural springs. In contrast, the other options refer to different bodies or forms of water. Lakes represent surface water bodies, while rainfall pertains to precipitation that replenishes surface water and can contribute to groundwater seepage but is not synonymous with groundwater itself. An irrigation system, on the other hand, describes a method used to supply water to crops and is not related to the definition of groundwater. Understanding the specific characteristics and significance of groundwater is essential in the context of environmental management and pesticide application, as it highlights the importance of protecting this resource from contamination.
