How does a cave form?

Answer 1

Caves form because ground water is slightly acidic and in flowing through joints, bedding-planes and faults within limestone or gypsum, dissolves the rock away. The only other rocks soluble in water are Chalk, Dolomite and Salt, but their formations do not normally support cave development - though there are a few caves known in chalk.

Answer 2

Over tens or hundreds of thousands of years, areas with limestone rocks can develop caves.

Caves are formed when carbonic acid in ground water dissolves limestone.

If the water level is lowered, then limestone dissolved from rocks above

the cave is deposited as stalactites and stalagmites.

Answer 3

what happened was:

1. the sea water around the poles used to be heated by the sun but the pole ice never melted.

2. This changed and instead the ice was being heated but the sea water was freezing up.

3. The whole Earth was covered in thick sheets of ice.

4. The ice melted and formed glaciers.

Answer 4

The large, pointed objects inside of caves are not icicles. Instead, they are calcium carbonate deposits that have formed from dripping mineralized water. These deposits are called "stalagmites" and "stalactites". Did you know that stalacmites and stalactites sometimes bond together to form a single column? ~Apple Juice

Answer 5

Caves are formed through the process of erosion, typically by water seeping through cracks in rock, slowly dissolving the rock over time. As the rock erodes, hollow spaces are created underground, eventually forming caves. Other factors such as tectonic activity and chemical weathering can also contribute to cave formation.

Answer 6

ice caves form when the inside of a glacier melts and the whole gets bigger and bigger
