The zone of aeration

The zone of aeration consists of the upper layers of soil in which there is air-filled porosity, pores or pockets filled with air rather than water. If toxic spills occur, chemicals move vertically through the zone of aeration and may penetrate the zone of saturation or ground water..

It may evaporate from the soil or be used by plants (zone of aeration, also called the vadose zone). Both air and water occupy the pore spaces. Excess water ...The zone of aeration consists of the upper layers of soil in which there is air-filled porosity, pores or pockets filled with air rather than water.

The movement of fluid through the zone of aeration can occur in several forms. Air moves in and out through the land surface in response to barometric pressure changes, oxygen enters the soil zone by diffusion as it is depleted by vegetation, water vapor moves out by diffusion and convection 151 R. W .Rain that falls on the surface seeps down through the soil and into a zone called the zone of aeration or unsaturated zone (also called the vadose zone), where most of the pore spaces are filled with air. As it penetrates deeper it eventually enters a zone where all pore spaces and fractures are filled with water.Groundwater starts life on the surface. When it rains and the water moves through the soil, it's called infiltration. The area near the surface of the soil is called the zone of aeration. There are spaces between the dirt and rocks that allow the water to flow through easily. Eventually the water makes it to rocks where scientists say it ...
