GEOLOGY

Detailed explanation-1: -The process of water soaking into the ground to become groundwater is known as groundwater recharge. The area on the surface where water soaks in is call the recharge area. There are several ways that groundwater might be recharge by rain: Rain soaks in where it falls and recharges the water table aquifer.

Detailed explanation-2: -The time it takes for surface infiltration to reach an aquifer as deep as 400 feet may take hours, days, or even years, depending on the rate of recharge. In some of the flood-irrigated areas, groundwater levels in nearby domestic wells rise within a few hours to days of flood-up.

Detailed explanation-3: -Water that seeps deep into the ground is called groundwater. Surface water and groundwater are reservoirs that can feed into each other. While surface water can seep underground to become groundwater, groundwater can resurface on land to replenish surface water.

Detailed explanation-4: -Fluctuations are generally due to one of three major factors including a change in the volume of water stored in the aquifer, changes in atmospheric pressure, and changes caused by aquifer deformation.
