GEOLOGY

Detailed explanation-1: -An aquifer is a body of rock and/or sediment that holds groundwater. Groundwater is the word used to describe precipitation that has infiltrated the soil beyond the surface and collected in empty spaces underground.

Detailed explanation-2: -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-3: -The upper surface of this water-filled area, or “zone of saturation", is called the water table. The saturated area beneath the water table is called an aquifer, and aquifers are huge storehouses of water.

Detailed explanation-4: -Aquifers must be both permeable and porous and include such rock types as sandstone, conglomerate, fractured limestone and unconsolidated sand and gravel. Fractured volcanic rocks such as columnar basalts also make good aquifers.
