Caves And Caverns Introduction. a cave is a natural hollow space under the ground that has an opening large enough for a person to enter. caves range in size from tiny passages to huge systems of connected “rooms” and tunnels. the world’s longest cave system is mammoth cave, in the u.s. state of kentucky. it is more than 350 miles (560 kilometers) long. Glacier, any large mass of perennial ice that originates on land by the recrystallization of snow or other forms of solid precipitation and that shows evidence of past or present flow. exact limits for the terms large, perennial, and flow cannot be set. except in size, a small snow patch that persists for more than one season is hydrologically. Glacial landform, any product of flowing ice and meltwater. such landforms are being produced today in glaciated areas, such as greenland, antarctica, and many of the world’s higher mountain ranges. in addition, large expansions of present day glaciers have recurred during the course of earth history. at the maximum of the last ice age, which. Formation process but most caves form in karst, a type of landscape made of limestone, dolomite, and gypsum rocks that slowly dissolve in the presence of water with a slightly acidic tinge.
