Types of cave formations
Glacier Caves Glacier caves are caves formed near the snouts of glaciers.
These randomized three-dimensional rooms form from a rising water table that erodes the carbonate rock with hydrogen-sulfide enriched water. When hot liquid lava flows down the slope of a volcano, the surface of the lava cools and solidifies. They were formed by H2S hydrogen sulfide gas rising from below, where reservoirs of oil give off sulfurous fumes.
Limestone caves facts
Cave pearls form when dissolved limestone within droplets falls into thin pools. Solution caves are formed when groundwater seeps underground via cracks, faults, joints, bedding places, and other surface openings. A sea cave in Thailand. Dogtooth Spar is a pool deposit that forms under extremely still conditions, where there is little or no water movement. A soda straw can turn into a stalactite if the hole at the bottom is blocked, or if the water begins flowing on the outside surface of the hollow tube. After a rain, water seeps into cracks and pores of soil and rock and percolates beneath the land surface. Generally there must be some zone of weakness to guide the water, such as a fault or joint. They occur in many parts of the world, and often contain highly specialized and endemic fauna. A special case is littoral caves, which are formed by wave action in zones of weakness in sea cliffs. It is also thought the bushes may have formed underwater when the water rising from below mixed with cave waters of a different chemistry.
Indeed, the morphology of caves and the life forms living in such environments are quite different from that of the outside world. After many drops have landed on the same spot a stalagmite has formed Figure 3.
Helictites are, perhaps, the most delicate of cave formations.

Facts about caves
Rift caves, lava mold caves, open vertical volcanic conduits, and inflationary caves can all form due to volcanic activity. Most caves are solutional caves, often called limestone caves for the common type of soluble rock in which they form. Photo by Andrew McMillan. The boulders associated with the talus caves are often the cause of landslides and rockfalls due to their unstable nature. Rock Shelters Rock shelters are produced when the bedrock erosion takes place in insoluble rocks. Solution caves are formed when groundwater seeps underground via cracks, faults, joints, bedding places, and other surface openings. This process slowly creates larger and larger crack and joints. All caves are not same but are vastly different depending on the process of formation and location of caves. Stalagmites are solid dripstones that grow upwards from the cave floor, from each drop of water from the roof or from stalactites overhead. Some sea caves can be accessed only by boats during low tide while others are more easily accessible and occur along beaches where it is possible to walk into the caves. By Oishimaya Sen Nag. Caves and their features form when rainwater follows the cracks or joints in the rock material, usually limestone or dolomite. It is 4. Sea caves might be small crevices or large chambers.
While small helictites are found in many caves, the helictite bushes are large, bush-like growths of calcite that branch and twist like gnarled trees.
Calcite rafts which litter the floor of some dry areas of the cave are evidence that these passages were once flooded too. Figure 4 : This Crystal Cave column is roughly 25 cm tall and 10 cm wide.
Here is a list of the different types of caves found in our world.
