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.

What is groundwater overuse?
Groundwater overuse occurs when the rate of water removal from an aquifer exceeds the rate of water recharge. This can lead to depletion of the groundwater supply, causing lower water levels, reduced stream flow, and land subsidence. Groundwater overuse can also result in saltwater intrusion in coastal areas.
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 can be caused by overpumping of groundwater?
Overpumping of groundwater can cause a drop in the water table, leading to land subsidence, reduced water availability for ecosystems and agriculture, intrusion of saline water into freshwater aquifers, and adverse impacts on local community water supplies.
What are the causes of land subsidence?
Land subsidence can be caused by natural processes like compaction of soil layers, underground erosion, or volcanic activity. Human activities such as groundwater extraction, oil and gas extraction, mining, and construction can also contribute to land subsidence. Over time, these processes lead to the gradual sinking or settling of the land surface.
What is the sinking of land due to the over pumping of ground water supplies called?
The sinking of land due to over-pumping of groundwater supplies is called land subsidence. This occurs when underground aquifers are depleted faster than they can be recharged, causing the land above them to sink or settle. Land subsidence can lead to infrastructure damage, decreased water quality, and other environmental issues.

Is a hazard in which an area of land sinks down due to the removal of underground material?
subsidence

The sinking land due to the over pumping of ground water?
The sinking of land due to over-pumping of groundwater is known as land subsidence. When excessive groundwater is extracted, the soil compresses, leading to the land surface sinking. This can result in infrastructure damage, increased flood risk, and other environmental problems. Implementing sustainable water management practices is critical to address and mitigate this issue.
How does a drought affect the lithosphere?
A drought can dry out the soil and vegetation on the lithosphere, leading to increased erosion and land degradation. The lack of water can also affect underground aquifers and cause land subsidence in areas with heavy groundwater extraction, impacting the stability of the lithosphere.
What is an example of subsidence?
an in-kind benefit
How does the overuse of groundwater affect groundwater?
Overuse of groundwater can lead to depletion of the water source, causing water tables to drop and wells to run dry. This can also result in land subsidence, saltwater intrusion into freshwater aquifers, and ecological harm to surrounding habitats that depend on groundwater.
What are two results of overuse of groundwater?
Two results of overuse of groundwater are depletion of aquifers, leading to lowered water tables and potential land subsidence, and saltwater intrusion into freshwater sources, making the water undrinkable.
What are some disadvantages of groundwater?
Some disadvantages of groundwater include depletion from overpumping, contamination from pollution or improper waste disposal, and subsidence of land due to excessive extraction. Groundwater depletion can lead to reduced water availability for ecosystems and communities that rely on it for drinking water and agriculture.
