Description and Pictures of the Various Cave Types Ice caves come in two forms. A cave formed entirely of ice is actually called a glacier cave and as the name implies, forms in glaciers. Water runs through or under the glacier and forms a cave. Glacier caves are very dangerous to enter and explore because of shifting and melting ice. They are a little too adventurous for the novice. The other type of ice cave can be any cave type (limestone, lava tube, etc.) that has ice in it year round. These caves trap cold air. Water entering the cave freezes and stays frozen year round.

Caving Caving – also traditionally known as spelunking in the United States and Canada and potholing in the United Kingdom and Ireland – is the recreational pastime of exploring wild cave systems. In contrast, speleology is the scientific study of caves and the cave environment. The challenges involved in caving vary according to the cave being visited, but – in addition to the total absence of light beyond the entrance – often include the negotiation of pitches, squeezes, and water hazards ...

A speleothem (pronounced /ˈspiːliːɵθɛm/ ; from the Greek for cave deposit), commonly known as a cave formation, is a secondary mineral deposit formed in a cave.Speleothems are typically formed in limestone or dolostone solutional caves.peleothems formed from salt, sulfur and other minerals are also known. Speleothems made of pure calcium carbonate are a translucent white color, but often speleothems are colored by minerals such as iron, copper or manganese, or may be brown because of mud and silt particulate inclusions.

Cave Corrasional or erosional caves are those that form entirely by erosion by flowing streams carrying rocks and other sediments. These can form in any type of rock, including hard rocks such as granite. Generally there must be some zone of weakness to guide the water, such as a fault or joint.aves form naturally by the weathering of rock and often extend deep underground. The word cave can also refer to much smaller openings such as sea caves, rock shelters, and grottos. Speleology is the science of exploration and study of all aspects of caves and the cave environment.

Cave A cave is a hollow place in the ground, specifically a natural underground space large enough for a human to enter. Caves form naturally by the weathering of rock and often extend deep underground. The word cave can also refer to much smaller openings such as sea caves, rock shelters, and grottos. A cavern is a specific type of cave, naturally formed in soluble rock with the ability to grow speleothems.

How Do Caves Form? Mammoth Cave, in Kentucky, a horizontal cave, is the longest cave system in the world, stretching for at least 390 miles (627 kilometers) beneath the surface of the Earth. However, some caves turn this tidy formula on its head and form from the bottom up. Water trapped in aquifers deep inside the Earth sometimes comes into contact with sulfide-loaded rocks, like pyrite, Orndorff said. This creates sulfuric acid, which, with enough hydraulic pressure, can push up through the rock to carve out a cave.
