A doline or shake-hole - and depending on the nature of both cave and collapse it can create an entrance to the cave.
A large hole in the ground formed when the roof of a cavern collapses is known as a sinkhole. Sinkholes can vary in size and are typically caused by natural processes such as erosion and the dissolution of soluble rocks like limestone.
The calcium deposit formed from water dripping through the roof of a cavern is called a stalactite. Stalactites hang from the roof of the cave and are formed as mineral-rich water drips down and leaves behind calcium deposits that slowly build up over time.
Sinkholes form typically as limestone dissolves. A caldera is created by the collapse of volcanic vault ceilings.
A cavern is an underground chamber formed by erosion
Two features formed by underground weathering are caves and sinkholes. Caves are formed by the dissolution of limestone or other soluble rocks, creating underground chambers and passages. Sinkholes are depressions in the ground that form when the roof of an underground cavern collapses.
A cavern roof is the uppermost part of a cave that forms the ceiling of the underground chamber. It is typically formed by the natural processes of erosion, weathering, and water seepage over time. Cavern roofs can vary in appearance and structure depending on the type of rock or material they are composed of.
sinkhole
The dripstone that grows down from the roof of a cavern is called a stalactite. Stalactites are formed by mineral-rich water dripping, leaving behind deposits of minerals such as calcite. Over time, these deposits build up and create elongated structures hanging from the cave ceiling.
stalactite- an icicle-shaped mineral deposit, usu. calcite or aragonite, hanging from the roof of a cavern, formed from the dripping of mineral-rich water. stalagmite- a conical mineral deposit, usu. calcite or aragonite, built up on the floor of a cavern, formed from the dripping of mineral-rich water.
stalactite
The icicle-like speleothem that grows down from the roof of a cavern is called a stalactite. Stalactites are formed by mineral-rich water dripping from the cave ceiling and depositing minerals as it hangs and drips downward. Over time, these mineral deposits build up to create the elongated, tapering structure we see in caves.
The Florida Caverns are limestone caves and were formed by rain water dissolving the limestone.
