cave, a cavity in the earth's surface usually large enough for a person to enter. Caves may be formed by the chemical and mechanical action of a stream upon soluble or soft rock, of rainwater seeping through soluble rock to the groundwater level, or of waves dashed against a rocky shore. Volcanic action (accompanied by the formation of gas pockets in lava or the melting of ice under lava) and earthquakes or other earth movements are also sources of cave formation. Limestone regions almost invariably have caves; some of these are notable for their stalactite and stalagmitestalactite and stalagmite
, mineral forms often found in caves; sometimes collectively called dripstone. A stalactite is an icicle-shaped mass of calcite attached to the roof of a limestone cavern.

The preserved remains of prehistoric humans and animals and indications of early human culture have been discovered in some caves. Caves have served as burial grounds and shelter since prehistoric times. One such cave is Alabama's Russell Cave, where human evidence dates back 9,000 years. Speleology, the scientific study of caves and their plant and animal life, contributes to knowledge of biological adaptation and evolution. Some cave animals lack sight, and both plants and animals living where light is excluded show loss of pigment. Deep cave ecosystems, lacking the sunlight necessary for photosynthesis, depend on bacteria that use chemosynthesischemosynthesis,
process in which carbohydrates are manufactured from carbon dioxide and water using chemical nutrients as the energy source, rather than the sunlight used for energy in photosynthesis. Much life on earth is fueled directly or indirectly by sunlight.

Among famous caves in the United States are Carlsbad Caverns National Park (N.Mex.), Mammoth Cave National Park (Ky.), Wind Cave National Park (Black Hills, S.Dak.), Luray Caverns (Va.), and Wyandotte Cave (Ind.). In Europe there are celebrated caves in Belgium, Dalmatia, Gibraltar, Capri, Sicily, Postojna, and England (Kent's Cavern and Kirkdale). The caves of the Pyrenees and the Dordogne are famed for their prehistoric paintings (see Paleolithic artPaleolithic art

Among the deepest known caves are Krubera in the nation of Georgia, which extends more than 6,500 ft (2,000 m) below the surface, and Lamprechtsofen in Austria. Bibliography See C. E. Mohr and T. L. Poulson, The Life of the Cave (1966); D. R. McClurg, The Amateur's Guide to Caves and Caving (1973). Cave a large cavity in the upper layers of the earth’s crust having openings that connect it to the surface of the earth. Caves are formed in many ways. Karst caves result from the leaching and erosion of such water-soluble rocks as limestones, dolomites, and gypsums. Others are formed as a result of the suffusion and underground erosion of weathered cracks (“clay pseudokarst”). Caves may be formed by abrasion, the deflation of particles resulting from the weathering of hard rocks, the formation of open tectonic cracks, and the uneven deposition of certain geological formations (for example, travertines). Lava caves form when the solidified crust of a lava flow ruptures and the fluid lava underneath flows out. Ice caves, or grottoes, form as a result of the thawing of ice. The largest caves are karst caves, which consist of intricate systems of passages and halls. Their total length is usually several dozen kilometers. Karst caves, particularly those of limestone, frequently have various types of colored dripstone and sinter formations, including stalactites, stalagmites, columns, and curtains. They also are characterized by underground streams, rivers, and lakes. Caves may be horizontal or may drop down steeply. Some consist of more or less horizontal cavities that alternate with steep and vertical underground passages descending to great depths. The deepest karst chasms in the world are the Pierre St. Martin Cave (1,171 m) and the Puits Berger (1,141 m), both of which are in France. Multistory caves occur frequently. The climatic regime of a cave depends on whether the cavity is directed upward from the entrance (warm caves) or downward (cold saclike caves). A cave may also have two outlets, providing good ventilation. Saclike caves and caves with through circulation have ice formations, such as crystals and icicles, year-round. Such caves are called ice caves (the Kungur Cave in the Ural region and the Balagansk Cave in the Angara River region). Caves are characterized by a unique fauna, some representatives of which are also found outside caves under similar conditions. Some caves were used as human dwellings during the Stone Age. Tools and the bones of extinct animals and primitive humans have been found in such caves. There are also drawings and paintings on the walls and ceilings. Stone Age caves include the Altamira Cave and the Kapova Cave. Speleology is the comprehensive study of caves. Many of the world’s caves are tourist attactions. REFERENCESGvozdetskii, N. A.

Special glasses make everything appear as 3D images and also track the path of the user's vision.
CAVE was the first virtual reality system to let multiple users participate in the experience simultaneously. Known as a "spatially immersive display," it was developed by the Electronic Visualization Laboratory at the University of Illinois in the early 1990s. See head mounted display and virtual reality.

Cave (dreams)Caves are rich and thought-provoking dream symbols. At times, a woman with reproductive issues may have a cave dream, in which case it represents the womb. The cave, as the womb, can represent new life, creativity, warmth, and safety. The cave can be a general symbol of a safe place, a sanctuary or a refuge. If you are experiencing much anxiety in daily life, in your dream state you may retreat to a warm cave where you cannot be disturbed by worldly demands. The cave could also represent the mysterious and unexplored parts of self. It could be symbolic of the unconscious mind, which could be a pleasant or a frightening experience. Your personal associations and experiences with caves, as well as the details and the emotional content of this dream, need to be carefully considered before making an interpretation.cave
