Explain with diagram, the position of water table aand aquifer. What is the difference between the two? Can water be taken out through a hand pump from an aquifer?
The water that is found under the surface of the Earth and is responsible for the presence of water in the wells, tube wells, and springs is called ground water. The porous regions in the soil and gaps in between the rocks are filled with this ground water. The upper limit of this layer of ground water, which fills into all the porous spaces between the soils, is called the water table.
Rain water and water from the other water bodies on the surface of the Earth seeps down into the soil and is stored as ground water. This passing down of water through the soil is known as infiltration.
This infiltrated water accumulates in the deep underground, where a layer of impermeable rocks blocks the water from seeping down further. Such places that have an impermeable layer of rocks leading to the accumulation of water over it are known as aquifers.
Yes, water can be pumped out from aquifer through a hand pump.
