How are caverns and sinkholes related?
Caverns and sinkholes are both formed in limestone bedrock by the process of dissolution, where groundwater dissolves the rock. Sinkholes are formed when the roof of a cavern collapses, resulting in a depression on the surface. So, caverns can be an intermediate stage in the formation of sinkholes.
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 formation that is dripped from the ceiling of a cave and forms a peak or column is called a stalactite. Stalactites are typically formed from the slow deposition of mineral-rich water, such as calcium carbonate, which drips down from the cave ceiling over time.
What do you call a cave entrance?
A cave entrance is commonly referred to as a cave mouth or cave opening.
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.
What is a example of a sinkhole?
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.
