Water in the ground occupies the volume between the individual grains of material in the rock or soil from which the ground is composed. Thus wet clay, for example, will shrink in volume as it drys out and cracks may appear too. A similar thing will occur if groundwater is removed and the land dries out - it will shrink (subsidence) and cracks may also appear.

The main reason for land subsidence is?
The removal of water from aquifers, such as fine grained sediments. The rock compacts because water is partly responsible for holding the ground up, and when the water is removed, the rock falls on itself.An excessive extraction of groundwater is the primary reason for land subsidence. This is particularly a problem in the southwestern United States.
What is the definition of a subsidence?
The definition of subsidence is the decreasing or caving in of an area of land. A real world example of a subsidence would be a sink hole, having the land sink in gradually.
The sinking land due to the over pumping of ground water?
subsidence.
What is the sinking of land due to the over pumping of ground water supplies called?
subsidence
How do you calculate subsidence rates?
survey the land or entire area with surveying equipment, look at previously recorded survey data from over the years, compare your findings with those previously taken, to see what the rate of subsidence is for the area.

Is a hazard in which an area of land sinks down due to the removal of underground material?
subsidence
How Many communities pump groundwater to irrigate crops and supply homes with water so how do you think over-pumping groundwater is related to the formations of sinkholes?
Many communities around the world rely on pumping groundwater for various purposes, including irrigation and water supply. Over-pumping groundwater can lead to the lowering of the water table, causing subsidence or sinking of the land surface. This subsidence increases the risk of sinkhole formation, as the ground becomes more prone to collapsing into underground cavities that were previously supported by groundwater.

Are there any problems caused by solution mining?
soolution mining can cause subsidence of land where the salt used to be. this could cause buildings to collapse and ground to be ruined
Land subsidence results from?
underground coal mining
The collapse of an aquifer from over pumping can reduce the storage capacity of the aquifer and cause?
land subsidence or sinking. This can lead to damage to infrastructure such as buildings, roads, and pipelines. It can also impact the availability of water resources, as the reduced storage capacity can result in decreased water availability for both humans and ecosystems.
The sinking land due to the over pumping of ground water?
subsidence.
A result of epeirogeny is?
Uplift and subsidence of large land masses without significant deformation.
What is the sinking of land due to the over pumping of ground water supplies called?
subsidence
What is the Meaning of subsidence?
Subsidence refers to the sinking or settling of the ground surface due to various factors such as mining activity, groundwater extraction, or natural processes like soil compaction. This can lead to structural damage to buildings and infrastructure above the affected area.
What do you call water that is stored beneath land?
Groundwater
