Question

classify lakes in three categories and give examples

Answer 1

Permanent lakesIn this kind of lakes, Evaporation < Precipitation.These lakes are deep and carry more water than could ever be evaporated.Example: Great Lakes of North AFresh water lakesMost of the lakes in the world are fresh-water lakes fed by rivers and with out-flowing streams e.g. Great Lakes of North America.Saline lakesSalt lakes (also called saline lakes) can form where there is no natural outlet or where the water evaporates rapidly and the drainage surface of the water table has a higher-than-normal salt content.Because of the intense evaporation (negative freshwater balance == more water is lost in evaporation than gained from rivers) these lakes are saline.Examples of salt lakes include Great Salt Lake, the Aral Sea and the Dead Sea.For example the Dead Sea has a salinity (salt content) of 250 parts per thousand, and the Great Salt Lake of Utah, U.S.A. has a salinity of 220 parts per thousand.Playas or salt lakes, are a common feature of deserts (recall desert landforms).merica, East African Rift Lakes.
