It's like a straw in a milkshake. If you suck hard enough, you see a dimple form around the straw.
Water is pulled out of the ground which leaves an air pocket in the space around the soil particles. Any nearby water around the air pocket flows into it, but it can only flow in the cracks between soil particles so it takes it a little time to get there.
If the pump is pumping out faster than the water is flowing in, the water table at the pump location begins to drawdown. The surrounding water table slopes down to the low spot which, from the side, makes a cone shape with curved walls.
The more you pump, the larger your cone. Soil with lots of clay in it has very small cracks between particles, so incoming (recharge) water gets there much more slowly. The walls of the cone will be steeper than in a sandy soil having plenty of void space for water to move through. Real ground is never just one kind of soil, though, and things are all mixed up in layers and clumps, so even with a soil test you're still only left with an educated guess as to how deep and how wide the actual cone will be.
A well causes a cone of depression by pumping water out of an aquifer faster than it can be replenished. This creates a lowered water table around the well, forming a cone-shaped depression. The size and shape of the cone of depression depend on factors such as the pumping rate, geology, and the aquifer's recharge rate.

When does a cone of depression form?
A cone of depression forms in an aquifer when groundwater is rapidly pumped from a well, creating a lowering of the water table around the well in a cone shape due to the water being drawn towards the well. This can result in nearby wells or surface water bodies experiencing reduced water levels.
In three words describe the shape of the water table around a pumping well?
Conical or cone-shaped.
What are the effects of a tropical depression?
A tropical depression can bring heavy showers and thunderstorms, which can cause flooding. Winds may reach gale force, not enough to cause any significant damage, but it can be a hazard for small boats.
Is there a cindre cone volcano in America?
Yes, there are several cinder cone volcanoes in America. One notable example is Sunset Crater in Arizona, which is a well-known cinder cone volcano in the United States.
Is Mount Kenya a composite cone a cinder cone or a shield cone?
Mount Kenya is neither a composite cone, cinder cone, nor a shield cone. It is a complex stratovolcano made up of layers of lava and ash.
How can a cone of depression cause a well to go dry?
A cone of depression forms when water is pumped from a well faster than it can be replenished by groundwater. This causes the water level around the well to drop, creating a cone-shaped depression in the water table. If the cone of depression extends below the depth of the well screen or pump intake, the well can go dry because no water is being drawn into the well.
What is the lowering of the water table that occurs when water is pumped from a well?
the cone of depression
When water is pumped from a well a depression is often produced in the water table Such a depression is called a?
Cone of depression
When water is pumped from a well a depression is often produced in the water table. Such a depression is a?
Cone of depression
When does a cone of depression form?

This picture shows a simple well that was dug down to the groundwater. What probably caused the lower level of groundwater known as a cone of depression in the vicinity of the well?
The cone of depression near the well is likely caused by pumping water out of the well faster than the groundwater can naturally replenish itself. This leads to a decrease in water levels around the well, creating a cone-shaped depression.
In three words describe the shape of the water table around a pumping well?
Conical or cone-shaped.
What does the lowering of water table that occurs when water is pumped from a well called?
The lowering of the water table that occurs when water is pumped from a well is called "cone of depression." This phenomenon happens because the pumping creates a cone-shaped cavity in the groundwater, causing the water table in the immediate vicinity of the well to drop.
What causes cone of depression in wells?
The weight of the atmosphere presses down on the groundwater in the well
What is lowered area of the water table found around a well caused by pumping water from the well?
The "drawdown" or "cone of depression".
Can depression cause brief psychosis?
Stress can cause Brief Reactive Psychosis, and it can cause Depression as well. so perhaps it can indirectly.
Can depression cause delusions?
Depression can very well cause delusions. But when this happens, it no longer is depression. If your seeing things out of the ordinary your depression could have turned into something much more serious like, physcotic depression.
