Question

______ is the shaping of the land present below the moving glacier.

  1. Glacier position
  2. Glacial erosion
  3. Glacial sedimentation
  4. Ice decomposition

hintHint:

Before this weathering occurs.

The correct answer is: Glacial erosion

The correct option is B)Glacial erosion.
Glacial erosion involves the removal and transport of bedrock and sediments through three major processes: quarrying (picking), abrasion and meltwater. Mining involves two separate processes: crushing the bedrock beneath the glacier and carrying the crushed rock along. Erosion by glacial meltwater under glaciers is the result of mechanical or chemical processes.

_________ causes weathering of rocks in glacier.

The correct option is b)Ice.
Ice wedges are defined by the physical weathering of rock, where the surface within rock cracks fills with water, freezes, and eventually expands. Widening cracks and build-up of pressure within the rock cause it to expand and fracture. Ice wedging is also called frost wedging.
