The crack marked on a glacier due to splitting of ice is called

watershed
crevasses
delta
glacier

The correct answer is B. crevasses.

A crevasse is a deep crack in a glacier, formed as the glacier moves and deforms. They can be very large, up to several hundred meters wide and deep, and can be very dangerous to cross.

A watershed is an area of land that drains into a particular river or stream.

A delta is a landform that forms at the mouth of a river, where the river meets the ocean.

A glacier is a large mass of ice that forms on land and moves slowly downhill under the force of gravity.
