Pulicat Lake is an example of which type of lake?

Correct answer: Lagoon lake

The direct answer is B, lagoon lake. A lagoon is a shallow water body separated partly from the sea by a sand bar, beach ridge or barrier spit, while remaining connected with the coastal environment. Pulicat Lake lies on the east coast of India near Andhra Pradesh and Tamil Nadu and is a coastal lagoon. The reasoning is: coastal location + shallow enclosed water + partial separation from the sea = lagoon. Option A, a glacial lake, forms when melting glaciers excavate or fill a basin, usually in mountains; Pulicat is not formed in that way. Option B is correct because Pulicat is a coastal lagoon. Option C, a volcanic lake, occupies a volcanic crater or caldera; Pulicat is not a volcanic basin. Option D, an oxbow lake, forms when a river meander is cut off; that is a river process, not Pulicat's coastal origin. Memory cue: Chilika and Pulicat are commonly remembered as Indian coastal lagoons.
