An aquifer is a body of rock and/or sediment that holds groundwater . Groundwater is the word used to describe precipitation that has infiltrated the soil beyond the surface and collected in empty spaces underground.
What is the simple definition of aquifer?
An aquifer is a body of rock and/or sediment that holds groundwater . Groundwater is the word used to describe precipitation that has infiltrated the soil beyond the surface and collected in empty spaces underground.
What is the best definition of an aquifer?
: a water-bearing stratum of permeable rock, sand, or gravel .
What is a aquifer kid definition?
Simply, aquifers are layers and areas of rocks below ground where all the cracks, crevices, and spaces between rock particles are full of water . ... The water is able to move through aquifers and people drill wells into them and pull the water out to use for their own uses.
What is an aquifer Class 7?
It is an underground layer composed of permeable rock, sediment, or soil that yields water . – An aquifer could be a body of porous rock or sediment saturated with groundwater. Groundwater enters through an aquifer as precipitation seeps through the soil.
Which is the example of aquifer?
A good example is the water of the Nubian Sandstone Aquifer System , which extends through several countries in an area that is now the Sahara. The water is being used extensively for water supply and irrigation purposes.
Where are aquifers found?
Aquifers Overview
Unlike surface water, which is mostly found in the northern and eastern parts of the state, aquifers are widely distributed throughout California . Additionally, they are also often found in places where freshwater is most needed, for instance, in the Central Valley and Los Angeles.
What is another name for an aquifer?

What are the three types of aquifers?
Aquifers are categorized as confined or unconfined, but there are many types of aquifers that are classified by where they are located in the earth and the material of which they are comprised. There are three types of aquifers: unconsolidated deposit aquifers, bedrock aquifers and quaternary aquifers .
How does an aquifer work?
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 3 things are needed for an aquifer to form?
Aquifers must be both permeable and porous and include such rock types as sandstone, conglomerate, fractured limestone and unconsolidated sand and gravel . Fractured volcanic rocks such as columnar basalts also make good aquifers.
What is the difference between water table and aquifer?
A water table describes the boundary between water-saturated ground and unsaturated ground . Below the water table, rocks and soil are full of water. Pockets of water existing below the water table are called aquifers. An area’s water table can fluctuate as water seeps downward from the surface.
What is aquifer short answer?
An aquifer is an underground layer of water-bearing permeable rock , rock fractures or unconsolidated materials (gravel, sand, or silt). Groundwater from aquifers can be extracted using a water well. The study of water flow in aquifers and the characterization of aquifers is called hydrogeology.
What is a node class 7?
Node: Node is a point on the stem (or branch) of a plant where a leaf is attached . Buds are also present in the node regions of a plant.
What are electromagnets Class 7?
An electromagnet is a type of magnet in which the magnetic field is produced by an electric current . The magnetic field disappears when the current is turned off. ... The wire turns are often wound around a magnetic core made from a ferromagnetic or ferrimagnetic material such as iron.
