Aquifer is the rock layer. More generally, it could be any permeable rock though, i.e. rock which through which water can pass either via a network of spaces between particles or along bedding planes, cracks, and fissures. Permeable rocks can become saturated. Examples of permeable rocks include limestone (which is heavily jointed) and chalk (porous).
An underground rock later that stores water is called an aquifer. Aquifers are important water sources in desert. Oases are usually centered around places where water seeps out from an aquifer. Also, people tap aquifers to access water in dry places. However, if an aquifer runs dry, parts of it may run the risk of collapsing, creating huge sinkholes that pull in anything above them.
An aquifer - a layer of permeable rock filled with water.
zone of saturation
The zone of aeration.
An underground layer of spongy rocks that holds water is an aquifer.

A large body of water that flows through land might be called a river. Another name for a large body of water that flows through land would be a canal.
An aquifer is not a type of water. It is an underground layer of permeable rock, sediment or soil that contains water. Wells are dug to reach this layer to obtain water.
its the fequair layer
Through pipes underground,then it flows into the river in which you got the water from in the first place.
An underground layer of spongy rocks that holds water is an aquifer.
1) underground water is being withdrawn and used constantly by people for cooking, drinking etc. 2) in urban areas, where the land surfaces are concrete and tarmac (non porous and very low permeability), water will not be able to infiltrate through, thus causing the water flows in the soil layer to decrease. Percolation, throughflow and baseflow are all decreased due to lack of water. This will cause the water table deep down in the soil layer to decrease in height, leading the lesser water being stored underground. Hope this answers your question!

It could be a spring or artesian well, from which water flows. Or a well in which water seeps rather than flows.
The springs that form where pressurized water flows through cracks in cap rock are called Artesian springs. This is the type of spring that feeds drinking wells.
zone of saturation
This is water cycle on Earth.
Gravity causes water to flow downwards. In porous ground the water will seep into the soil. If the water hits a non-porous layer (clay, for instance) the water will spread horizontally.
As more water flows through a river, its speed will increase.
