aquifer-is a wet underground layer of water-bearing permeable rock or unconsolidated materials (gravel, Sand, silt, or clay) from which groundwater can be usefully extracted using a water well.
WHILE
Aquiclude-An impermeable body of rock or stratum of sediment that acts as a barrier to the flow of groundwater
An aquifer is a permeable underground layer that holds water and allows it to flow, while an aquitard is a dense, impermeable layer that restricts or inhibits the flow of water. Aquifers can store and transmit water easily, while aquitards act as barriers preventing water movement.

What do mean by the term aquitard?
An aquitard is a geologic formation that has low permeability and restricts the flow of water, acting as a barrier to groundwater movement. It has the ability to slow down the movement of water but generally does not completely prevent water flow.
What is the bedrock below an aquifer called?
The bedrock below an aquifer is called the water table. For example if a hole is dug into sand, very wet and saturated sand at shallow depth this would represent the aquifer and the level to which the water rises in this hole would be called the water table.
What are some harmful effects of aquifer depletion?
The aquifer cannot be recharged fast enough
What are the disadvantages of using groundwater?
There are several problems: # This aquifer carries water to the oceans, just like above ground rivers do. This cuts off a nutrient and thermal source that ocean life depends on. # This aquifer commonly supports the land above it, so removing the water can create sink holes. # This aquifer commonly supplies multiple wells, so removing water at a new place may change how much and how deep others may have to go, and what contaminants they will see. # This aquifer frequently contains things that are unsafe to be drunk, so additional treament will be necessary. (Water quality usually changes more slowly for groundwater sources, than does a river, so that helps.) # Drawing water from this aquifer draws additional organisms from the vadose zone (and above), which will alter water quality over time. # The hole fails over time (ground settles, casings corrode, other wells lower water table), and additional expense has to be spent on into the future to maintain / repair / abandon it.
Where is the edwards aquifer in relation to the ogallala aquifer?
The Edwards Aquifer is located in south-central Texas, primarily under the San Antonio region, while the Ogallala Aquifer is located in the Great Plains region of the United States, extending from South Dakota to Texas. The Ogallala Aquifer is geographically north of the Edwards Aquifer.
Is an aquitard porous or impermeable?
An aquitard is a relatively impermeable layer of rock or sediment that slows down the movement of water but does not completely prevent it. It has low permeability compared to an aquifer, allowing water to flow through but at a slower rate.
What do mean by the term aquitard?
An aquitard is a geologic formation that has low permeability and restricts the flow of water, acting as a barrier to groundwater movement. It has the ability to slow down the movement of water but generally does not completely prevent water flow.
What is the difference between an aquifer and an aquitard?
An aquifer is a permeable rock or sediment layer that can hold water and transmit it freely, while an aquitard is a low-permeability layer that restricts the flow of water between aquifers. In other words, an aquifer stores and transmits water, while an aquitard acts as a barrier to water flow.
What is the bedrock below an aquifer called?
The bedrock below an aquifer is called the water table. For example if a hole is dug into sand, very wet and saturated sand at shallow depth this would represent the aquifer and the level to which the water rises in this hole would be called the water table.
What is an aquitard?
If you are talking about science, then an aquitard is an impervious layer of clay, silt, or rock that will not allow the water to pass through it fast enough to be used as a water supply.Geological formation that may contain groundwater but is not capable of transmitting significant quantities of it under normal hydraulic gradients. May function as confining bed.
Clay in aquifer is know as a good?
Clay in an aquifer is known as a good aquitard, which restricts the flow of water due to its low permeability. This can help in preventing contamination of groundwater by acting as a barrier. Additionally, clay can also serve as a natural filter, trapping and retaining fine particles and impurities present in the water.
How does Aquitard affect the movement of water underground?
Aquitards slow down the movement of water underground because they have lower permeability compared to aquifers. They act as barriers that limit the flow of water, causing water to accumulate and creating pressure. This can impact the flow and storage of groundwater in an area.
How do you spell aquifer?
aquifer.
Which aquifer is NOT part of the greater Mountain Aquifer system?
Northern Aquifer
How are aquifers and aqueducts alike and different?
An aquifer is natrually made and a aqueduct is man made channel of pipes
How are aquifer and reservoir the same how are they different?
A reservoir is a big land mass that holds water "supplies" an aquifer is the same thing is just small and you could say that it purifies the water that it holds.
What is an antonym for aquifer?
The word aquifer does not have an antonym.
