Compare and contrast erosional and depositional glacial landforms. How do they form? Provide
examples. What will be an ideal response?
Depositional glacial landforms include moraines, outwash plains, varves, etc. They form by the
deposition of materials that are eroded by the movement of glaciers. Erosional features include
glacial striations, polished bedrock, ice-scoured plains, U-shaped glacial valleys, etc. They form
by the direct erosion of land surfaces by glaciers.
