Results for “Rift Valley lake”

Rift Valley lake

Generic term for any lake formed in a rift valley, but often used in specific reference to a group located in the East African rift, particularly those lying in its western and southern sections, i.e., the African Great Lakes. In the aquarium hobby the meaning of the term is typically restricted even further to include just lakes Malawi, Tanganyika, and Victoria, the latter of which is not in fact a rift lake and is located in a shallow depression between the eastern and western branches of the main rift. These three lakes are famous for the high number of endemic fish species inhabiting them, especially members of the family Cichlidae.

rift

Narrow fissure or zone of faulting formed via tensional stress in the earth's crust. When such forces are strong or prolonged enough to split the crust apart a central section will typically drop down or subside, sometimes forming a rift valley with steep walls as the gap widens. Water may become impounded in the valley, forming a rift lake.
