GEOLOGY

Detailed explanation-1: -groundwater, water that occurs below the surface of Earth, where it occupies all or part of the void spaces in soils or geologic strata. It is also called subsurface water to distinguish it from surface water, which is found in large bodies like the oceans or lakes or which flows overland in streams.

Detailed explanation-2: -Earth has three layers: the crust, the mantle, and the core. The crust is made of solid rocks and minerals. Beneath the crust is the mantle, which is also mostly solid rocks and minerals, but punctuated by malleable areas of semi-solid magma. At the center of the Earth is a hot, dense metal core.

Detailed explanation-3: -The term aquifer refers to water-bearing foundations or rocks that can hold large amounts of water. Aquifers are a huge storehouse of Earth’s water and people all over the world depend on groundwater in their daily lives. The top of the surface where groundwater occurs is called the water table.

Detailed explanation-4: -Groundwater is water that has infiltrated the ground to fill the spaces between sediments and cracks in rock. Groundwater is fed by precipitation and can resurface to replenish streams, rivers, and lakes.
