What is a aquifer short answer?

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.

What is water aquifer?

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 is a aquifer kid definition?

An aquifer is a collection of wet, underground rocks that allows water to pass through it slowly. A well can be used to pump water from an aquifer so people can use the water for drinking, watering crops, and other purposes.

What is an aquifer example?

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.

What is aquifer in environmental engineering?

An aquifer is a saturated formation of earth material which not only stores water but yields it in sufficient quantity. Or. The water bearing strata or formation. Thus an aquifer transmits water relatively easily due to its high permeability.

Which is the best aquifer?

Good aquifers are those with high permeability such as poorly cemented sands, gravels, or highly fractured rock. An aquitard is a body of material with very low permeability. In general, tightly packed clays, well cemented sandstones, and igneous and metamorphic rocks lacking fractures are good aquitards.

Where are most aquifers located?

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 an aquifer layer made of?

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.

Is shale an aquifer?

Many of the sandstone aquifers in the United States are embedded in shale and siltstone. As a result, the water in these aquifers are considered to be in confined condition because the surrounding rock is impermeable.

Is clay an aquifer?

Groundwater below a layer of solid rock or clay is said to be in a confined aquifer. The rock or clay is called a confining layer. A well that goes through a confining layer is known as an artesian well. The groundwater in confined aquifers is usually under pressure.

Is a sandstone an aquifer?

The sandstone aquifers are level or gently dip. Because they are commonly interbedded with siltstone or shale, most of the water in these aquifers is under confined conditions. Groundwater-flow systems in mostly level, relatively thin sandstone aquifers are local to intermediate.

Which rock is aquifer?

sandstone

An aquifer is a body of saturated rock through which water can easily move. 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.

How do you find an aquifer?

Sand or gravel areas in the bottom of valleys will often be home to groundwater. These layers can be covered by clay or silt, so it's prudent to check these areas thoroughly. Natural springs usually indicate groundwater is nearby. A spring that flows year-round will likely reveal a productive aquifer.

What is sedimentation rock?

Sedimentary rocks are formed from pre-existing rocks or pieces of once-living organisms. They form from deposits that accumulate on the Earth's surface. Sedimentary rocks often have distinctive layering or bedding.

How does the rock act as aquifer?

An aquifer is defined as a body of rock or unconsolidated sediment that has sufficient permeability to allow water to flow through it. Unconsolidated materials like gravel, sand, and even silt make relatively good aquifers, as do rocks like sandstone. Other rocks can be good aquifers if they are well fractured.

How does water become groundwater?

Groundwater begins as rain or snow that falls to the ground. This is called precipitation. Only a small portion of this precipitation will become groundwater. Most will run off the land surface to become part of a stream, lake or other body of water.

What is an aquifer quizlet?

Aquifer. A natural underground area where large quantities of ground water fill the spaces between rocks and sediment.

What is an aquifer and why is it important quizlet?

Aquifer = region where ground water is stored and retained that must be large enough and be able to move water at a fast enough rate to be hydrologically significant.

How do aquifers work quizlet?

the zone immediately below the land surface where the pores contain both water and air, but are not totally saturated with water. Plant roots can capture the moisture passing through this zone, but it cannot provide water for wells. Aka the unsaturated zone.

Is the water table flat?

Generally, the water table is deeper beneath hills and shallower Page 2 beneath valleys. It is hardly ever flat! In any one place the water table usually rises with increased recharge from precipitation and declines in response to seasonally dry weather, drought, or excessive pumping of ground water.
