Solution
The level where all spaces between soil is filled with water or the upper surface of groundwater is called water table.
Deforestation and over-pumping of groundwater results in lowering of water table.
Deforestation is the process of clearing forest land of trees and plants and turning it to commercial or residential use. It has a negative impact on the groundwater table.
Groundwater levels are depleted as a result of excessive pumping.
