When a water-bearing rock readily transmits water to wells and springs, it is called an aquifer. Wells can be drilled into the aquifers and water can be pumped out. Precipitation eventually adds water (recharge) into the porous rock of the aquifer.

What causes aquifers to form?
Similar to a below-ground sponge, aquifers are the natural accumulation of runoff and precipitation. Below the surface, this runoff then percolates into crevices between rocks, silt and other material.
How are aquifers made?
An aquifer is a body of porous rock or sediment saturated with groundwater. Groundwater enters an aquifer as precipitation seeps through the soil. It can move through the aquifer and resurface through springs and wells.
Where do aquifers usually form?
Groundwater can be found in a range of different types of rock, but the most productive aquifers are found in porous, permeable rock such as sandstone, or the open cavities and caves of limestone aquifers.
How is groundwater and aquifer formed naturally?
Groundwater is naturally replenished by surface water from precipitation, streams, and rivers when this recharge reaches the water table.
What are aquifers and how are they formed?
An aquifer fills with water from rain or melted snow that drains into the ground. In certain areas, water could pass through the soil of the aquifer while in other areas it enters through joints and cracks in rocks where it moves downwards until it encounters rocks that are less permeable.
When were aquifers formed?
The reserves formed when ocean levels were lower and rainwater made its way into the ground in land areas that were not submerged until the ice age ended 20,000 years ago.
Are aquifers formed quickly?
Aquifers are filled slowly. For this reason, aquifers can dry up when people drain them faster than they can be refilled—a process called aquifer depletion.
What is meant aquifer?
aquifer, in hydrology, rock layer that contains water and releases it in appreciable amounts. The rock contains water-filled pore spaces, and, when the spaces are connected, the water is able to flow through the matrix of the rock. An aquifer also may be called a water-bearing stratum, lens, or zone.
Do aquifers dry up?
Depending on geologic and hydrologic conditions of the aquifer, the impact on the level of the water table can be short-lived or last for decades, and it can fall a small amount or many hundreds of feet. Excessive pumping can lower the water table so much that the wells no longer supply water—they can "go dry."
How are aquifers replenished?
Most aquifers are naturally recharged by rainfall or other surface water that infiltrates into the ground. ... The stored water is available for use in dry years when surface water supplies may be low.
What is an aquifer and why is it important?
Aquifers are bodies of saturated rock and sediment through which water can move, and they provide 99% of our groundwater. Humans rely on aquifers for most of our drinking water.
What is an aquifer short answer?
An aquifer is an underground layer where the material contains water. That can be less solid material like sand, gravel, clay or silt, but it can be rock as well, as long as the rock allows water to get in (that means that it is water-bearing). From such layers or groundwater can be usefully extracted using a well.
Can you build an aquifer?
Therefore, an aquifer that has high permeability, like sandstone, will be able to hold more water, than materials that have a lower porosity and permeability. You will build your own aquifers and investigate which sediments hold more water (rocks or sand).
What is an example of an aquifer?
An example of an aquifer is The Great Artesian Basin. An underground layer of water-bearing porous stone, earth, or gravel. ... An underground layer of permeable rock, sediment, or soil that yields water. Aquifers can range from a few square kilometers to thousands of square kilometers in size.
How do you identify an aquifer?
The ground penetrating radar (GPR) system is used for underground water detection. GPR is a promising technology to detect and identify aquifer water or nonmetallic mines. One of the most serious components for the performance of GPR is the antenna system.
