When a rock above a cave collapses it forms a what?
When rock above a cave collapses, a sinkhole is formed.
What is formed when rock above a cave collapses it forms a?
When rock above a cave collapses, it forms a sinkhole. Sinkholes are depressions in the ground that are often caused by the erosion of underground caves or channels.

When the rock above a cave collapses it forms an?
A shakehole (or sinkhole) - it can form an entrance to the cave, or block it entirely. Also swallow hole. It's important to realise that the existence of a shakehole does not necessarily mean an enterable cave lies below: the dissolved carbonate rock below may have been carried away in a multitude of fine conduits as in chalk, rather than a discreet passage.
How is a boulder cave formed?
A Boulder, or Talus Cave rather stretches the definition of "cave", but it's simply a void or set of voids left between fallen boulders and their source rock-face. A cave's chamber that is heavily obstructed or even terminated by collapsed rock is often called a "boulder chamber", but it's not correct to say that collapses form caves. They don't - they modify them.
Substance of which the stalagmites are formed?
Calcite, usually, from the limestone above the cave. (Or gypsum, if the cave is in that rock)

How are boulders formed?
A Boulder, or Talus, Cave is simply an enterable void or set of voids between boulders and the rock-face from which they have fallen. Collapses within existing karst, sea or lava caves may choke the passage or chamber with boulders, and such chambers are often called "boulder chambers", but that does not form the cave, and it is not the same as a true boulder cave.

Why do sinkholes appear on the ground?
Sinkholes often occur when underground rivers erode the rock beneath the Earth's surface. Eventually, the land above is no longer sufficiently supported and collapses into the cave that has developed beneath it. They are more common in places with limestone, as it is easily eroded.
