Question

Winding ridges of sand and small bits of gravel formed from the outwash of a melting glacier are called _______.

Answer 1

Winding ridges of 'sand' and 'small bits of gravel' formed from the out-wash of a 'melting glacier' are called eskers.

Step-by-step explanation:

• Eskers are usually found in stratified form and are evident of the fact that the region where they are found was once glaciated.

• It is due to the continued pressure applied by the glacier for a long time, the sand and gravel get stratified under the glacier and are exposed after the melting out of the glacier.

Answer 2

Moraine. The glacial formation of the collection of loosely arranged glacial debris which may include rock, sand, and soil that occurs in recently glaciated and previously glaciated parts on Earth is called moraine. It may contain debris ranging in size from sand-sized glacial flour to huge boulders.
