Groundwater is defined as water that is found beneath the surface of the earth in conditions of 100 percent saturation (if is less than 100 percent saturation,then the water is considered soil moisture).Ninety-eight percent of earth’s available fresh water is groundwater
The “powerhouses” of the cell, mitochondria are oval-shaped organelles found in most eukaryotic cells. As the site of cellular respiration, mitochondria serve to transform molecules such as glucose into an energy molecule known as ATP (adenosine triphosphate).
For the answer to the question above,
An area where soil has eroded experience <u>"</u><u>loss of nutrients. "</u>
The topmost layer of soil is called the topsoil and is the most fertile. Soil erosion results in the loss of soil fertility and makes the land barren
The main cause of soil erosion is the removal of vegetation, which exposes the topsoil to water and wind. Wind and water are the main agents of soil erosion.
Water erosion can be sheet erosion, rill erosion, gully erosion or riparian erosion.
