cave 1. An underground hollow with access from the ground surface or from the sea, often found in limestone areas and on rocky coastlines. 2. A natural cavity, chamber or recess which leads beneath the surface of the earth, generally in a horizontal or obliquely inclined direction. It may be in the form of a passage or a gallery, its shape depending in part on the joint pattern or structure of the rock and partly on the type of process involved in its excavation. Thus, caves worn by subterranean rivers may be different in character from, and of considerably greater extent than, a sea-cave eroded by marine waves. 3. A natural underground open space, generally with a connection to the surface and large enough for a person to enter. The most common type of cave is formed in a limestone by dissolution (1. Podzemna votlina, ki je dostopna s kopenskega površja ali morja, pogosto najdena na apnenčastem območju in kamnitih obalah. 2. Naravna razpoka, prostor ali niša, ki vodi pod zemeljsko površje, ponavadi leži v vodoravni ali rahlo nagnjeni smeri. Lahko ima obliko hodnika ali galerije, njeno obliko pa delno določata kamninska sestava in procesi, katerim je izpostavljena. Tako je jama, ki jo izoblikuje podzemna reka drugačna in se obenem močno razlikuje od tiste, ki je rezultat erozije morskih valov. 3. Naraven podzemen odprt prostor, v večini primerov povezan s površjem in dovolj velik, da lahko vanj vstopi človek. Najpogostejši tip jame nastane s korozijo apnenca) |
