Layer of freezing/frozen water on the top of a river, ice or land is termed as ______ .

  • A.Naleds
  • B.Cirque
  • C.Snow cap
  • D.Snow line

Answer: A

The layer is called Naleds.

A naled (also called aufeis or icing) is a sheet of ice built up when water seeping from a river, spring or the ground spreads over the surface and freezes layer upon layer, on top of a frozen river or land. They are common in cold regions with permafrost.

A cirque is a bowl-shaped hollow carved by a glacier at the head of a valley. A snow cap is a covering of snow on a mountain top, and the snow line is the altitude above which snow lies all year. None of these is a layer of frozen water on a river or land surface.
