Caving offer many attractions, both playful and scientists at various levels, which makes it a very full activity. Global way, we can distinguish several types of caving, depending on the type of cavity in which they develop. As practiced in the caves with longer lengths and slopes of the planet can be considered as the main branch of caving exploration; the scanning conditions are also usually hard. The cave diving is the most complicated and difficult variant of caving that focuses on exploring underwater cavities. Many of the caves in just blinded by water pipes, called siphons. From this point, cave divers to take over cavers to continue exploration of the cavity.

A cave or cavern is a natural cavity in the ground caused by some kind of erosion of flowing water, ice or lava, or less commonly, a combination of several of these factors. In the most common case, the caves are formed by the dissolution of limestone by the water slightly acidic. Sometimes it is suitable to serve as a shelter for animals and humans, which can be equipped for housing in the form of cave houses and other human uses. They are usually damp and dark. The secondary caves or epigenetic originate within the rocks after they themselves have been formed by processes in which the host rock and material is lost through erosion. Secondary caves are also formed by tectonic processes that do not break the rock, but the fracture, such as joints and Trollegater. People who study caves are called cavers. The mud and moisture impose the use of waterproof clothing; other essential items of equipment are nylon ropes, helmets and lamps equipped with steel cable ladders. Cavers can work together and stay in a cave for several days. It is a dangerous activity: rain can cause flooding of the cave or produce rockfall.

Stalactites and stalagmites are thin limestone formations hanging from the ceiling. The water seeping becomes a white mineral called calcite; to dry the water accumulates mineral, then the stalactite forms in a very slow process of a century. In turn they may originate in the soil formations taking taper slow drip product, these formations are called stalagmites.

A volcanic cave is any cavity formed in volcanic rocks, although common use of this term is reserved for primary caves or singenéticas created by volcanic processes so that both the cavity and the surrounding rock are formed simultaneously. The sea caves and other erosive cavities may be formed in volcanic terrains, but are not related to volcanic processes and is normally generate much after forming the host rock, and is therefore secondary cave or epigenetic. Caves in this Article are solely naturally formed cavities. Cavities caused by geological processes.

Thus, resulting from human activities such as cavities are mines, rock tombs, hypogea, catacombs, air raid shelters, basements or artificial caves are no caves by standard definition, but actually look like real caves. Primary caves are caves that have arisen simultaneously with the rock surrounding it. Numerous small primary caves were formed when in the formation of carbonate sediments the cavities during sedimentation were left out, or they were created before the processes of cementation or diagenesis inserting. Also common are lava caves. Often there are small cavities, caused by gas bubbles in solidifying lava. Most of these cavities are opened only by chance. But there are also many kilometers long lava caves. These so-called lava tubes are lava tubes, whose surface is cooled and solidified, while including further flowed the lava until the eruption came to a halt. Such caves are found about on Hawaii, in Iceland and the Canary Islands.

Secondary caves are caves, as they have arisen surrounding rock later. This category includes caves by corrosion, erosion, mechanical weathering, tectonics of the earth or rock layers or a combination of these influences have emerged. Secondary caves can be found in rocks that are water soluble in the broadest sense, especially in the various types of limestones. Rain water contains carbon dioxide, which can solve it depending on its temperature. Colder water can dissolve more carbon dioxide. Depending on the carbon dioxide concentration of the water generates the carbonic acid weathering of the lime. By capillary action, the water penetrates into fine crevices of the rock and dissolves lime. That alone explains no significant cave formation.
