Of this 3% freshwater, 30% is groundwater, which is difficult to access, and 69% is found in the form of icebergs and glaciers. Only 0.006% of the remaining 1% of water is used by people for their purposes (not accessible).
The term "water cycle" refers to the ever-present flow of water either above or below the earth's surface.
The earth's water balance is relatively steady over time, however, individual molecules of water can enter and exit the atmosphere.
Water is found in the pore spaces of soil and the cracks in rock formations beneath the surface of the earth.
The topmost stratum is the water table.
Below the water table is where groundwater is located.
Infiltration: The process of water seeping into the earth is referred to as infiltration.
Aquifer: below the water table, water is held between layers of hard rocks and is referred to as an aquifer.
If we continue to extract more water from a location than is being replenished by rainfall, the water table of that location may drop. Depletion of the water table can be caused by several factors:
Most of the time, rainwater that falls on earth is left to run off.
On the other hand, it can be preserved and utilized to raise Earth's groundwater levels. rainfall harvesting is the practice of keeping rainfall from evaporating and storing it for use in domestic or commercial settings, such as recharging groundwater supplies or completing home tasks.
