Erosion and Deposition: Water and Ice — Quiz

Question 1 • Earth and Space Science

Which statement best explains how drumlins form in glacial environments?

Answer
A
Ice melts and creates depressions filled with water.
B
Glacial ice shapes sediment into streamlined hills.
C
Rainwater dissolves underground rock to form voids.
D
Wind smooths the surface of exposed rock.

Explanation

Drumlins are elongated, streamlined hills made of sediment that are shaped beneath moving glacial ice. The ice molds and deposits sediment into their characteristic form, so “Glacial ice shapes sediment into streamlined hills” is the best explanation. Melting ice, dissolving rock, and wind erosion do not form drumlins.
