How Are Caves formed?
First, we would like to acquaint you with the caves in general. A cave is a natural void in the ground, a hillside or cliff, specifically a natural opening in the earth which is large enough for a human to enter through the cave’s mouth. There is no certain dimension for the mouth of caves; the entrance might be very small, so that one needs to crawl into the cave through the mouth, or it might be an opening of several meters.
Caves are formed either naturally or artificially.
Artificial caves are created by humans, in the form of holes, ditches or cracks in rocks or in the ground. Artificial caves are created for various purposes including protection of humans against animals, natural disasters, wars and so on.
The reasons of formation of different natural caves are as follows:
1. Acidic water (carbonic acid) flowing down through the cracks in the limestone
2. Sea wave erosion
3. Earthquakes and folding in rock layers
6. Ice Caves
