Heifer – a cow that has not borne a calf, or has borne only one calf. In North America, a typical farm has about 100 milk cows and as many young female stock called heifers. The heifers are raised as replacement cows.
Karst topography is a result of the dissolution of soluble rocks like limestone, dolomite and gypsum. Caves are formed due to weathering of rock deep underground. Cave or cavern is a natural void and is a space large enough so that a human can enter. The study of the formation and development of caves is called as Speleogenesis. Most of the formation of caves takes place in limestone rocks by dissolution.
