Question

How do glaciers acquire their load of sediment?

Options:
A) Sediments are deposited on glaciers by streams that flow into the glaciers.
B) Sediments are plowed up into the glacier by the front terminus of the glacier as it moves downhill.
C) Sediments are plucked off the rocks at the base and sides of the glacier.
D) Sediments fall off the cliffs surrounding the glacier and move through crevasses to the base of the glacier.
E) All of the answers describe major contributors to the glacial sediment load.

Answer 1

Glaciers collect sediments through various sources, including deposition by streams, plowing up materials from the ground, plucking sediments from rocks, and from falls through crevasses, with all described methods being significant contributors.

The correct option is A.

Step-by-step explanation:

Glaciers acquire their load of sediment through a variety of processes. Sediments are indeed deposited on glaciers by streams that flow into them, and as glaciers move, they plow up and incorporate materials from the ground via the glacier's terminus, which is the end or edge of the glacier.

Additionally, sediments are plucked off the rocks at the base and sides of the glacier through a process known as plucking. Sediments can also fall into the glacier from cliffs surrounding it, moving through crevasses to the base. Therefore, all of the answers describe major contributors to the glacial sediment load.

The correct option is A.
