GENERAL GEOLOGY

Detailed explanation-1: -The soil surface above the water table is called the unsaturated zone, where both oxygen and water fill the spaces between sediments. The unsaturated zone is also called the zone of aeration due to the presence of oxygen in the soil.

Detailed explanation-2: -ZONE OF AERATION: The area of an unconfined aquifer above the water table where the pore spaces among soil particles and rock formations are filled with air.

Detailed explanation-3: -Groundwater is all the water that has penetrated the earth’s surface and is found in one of two soil layers. The one nearest the surface is the “zone of aeration", where gaps between soil are filled with both air and water.

Detailed explanation-4: -The vadose water is further subdivided into three zones, i.e., soil water zone, intermediate zone and capillary zone.

Detailed explanation-5: -Zone of aeration and zone of saturation are two layers on earth’s surface. The zone of aeration lies between the earth’s surface and the water table. Zone of saturation lies beneath the water table.
