How are caverns and sinkholes related?
Caves are underground. They are big long holes underground. Sometimes, for some unknown reason, the roof of the cave can no longer support the weight of the ground above it and the ground collapses down into the cave. The land sinks. It fills the hole. Where there was a cave, there is now solid ground. Where there was land, there is now a big hole. So, you have a sinkhole when the roof of a cave collapses.
Is a sea arch formed by erosion or by deposition?
A sea arch is formed primarily by erosion. As waves erode the coastline, they create a hole or cave in a headland. Over time, this continual erosion causes the cave to expand from both sides until it forms an arch.
How is a stack stump or caves formed?
A stack is formed when the roof of a sea cave collapses, leaving a pillar of rock separate from the mainland. Stumps are the remnants of a stack that has eroded further causing it to collapse. Caves are formed by the erosion of coastal rock by the action of waves, often in softer rock types that are easily worn away.
What is a limestone that is dripped from the ceiling of a cave forming a peak or column?
The limestone, or more accurately its calcium carbonate,has been dissolved from the rock above, in the joints through which the ground-water passes before dripping into the cave. The mineral is then precipitated in the cave air as Calcite, to form a Stalactite on the celing, and a Stalagmite on the floor below. A "column" is simply a stalactite and stalagmite that have met.
What do you call a cave entrance?
The opening is called the cave entrance or cave mouth. It is usually an "exit" formed by flowing water.
When a rock above a cave collapses it forms a what?
When rock above a cave collapses, a sinkhole is formed.
When the rock above a cave collapses forms a what?
It is called weathering.
A circular depression formed when the roof of a cave collapses?
A sinkhole forms.
What is a circuler depression formed when the roof of a cave collapses?
Shakehole or Sinkhole - when the collapse extends to the surface. (Not all cave roof collapses disturb the surface above.)
What geological feture is formed when the roof of a cave collapes?
A sinkhole is formed when the roof of a cave collapses.
When a rock above a cave collapses what does it form?
It is called weathering.
When a rock above a cave collapse it forms what?
It is called weathering.
When the rock above a cave collapses what does it form?
When the rock above a cave collapses, it can form a sinkhole if the collapse creates a depression in the ground. This can sometimes lead to the formation of a sinkhole cave system underground.
When a rock above a cave collapses it form a?
It is called weathering.
What is an example of a sinkhole?
A large hole formed when a roof of a cave collapses.

A large hole formed when a roof of a cave collapses.
What is a hole on the surface of the ground that forms when a cave collapses called?
A sinkhole.
