GEOLOGY

Detailed explanation-1: -Aquifers are typically made up of gravel, sand, sandstone, or fractured rock, like limestone. Water can move through these materials because they have large connected spaces that make them permeable.

Detailed explanation-2: -Groundwater, as the name implies, is water found below the surface of the Earth. Water from rains and snowfall infiltrates soil and other permeable surfaces. Groundwater can be divide into two major zones: unsaturated and saturated.

Detailed explanation-3: -Many different types of sediments and rocks can form aquifers, including gravel, sandstone, conglomerates, and fractured limestone.

Detailed explanation-4: -Over 68 percent of the fresh water on Earth is found in icecaps and glaciers, and just over 30 percent is found in ground water. Only about 0.3 percent of our fresh water is found in the surface water of lakes, rivers, and swamps.

Detailed explanation-5: -2.1. Confined aquifers. Confined Aquifers are those bodies of water found accumulating in a permeable rock and are been enclosed by two impermeable rock layers or rock bodies. 2.2. Unconfined aquifer.
