During which process does soil transport occur via glaciers?

• A. Wind erosion
• B. Gravity movement
• C. Glacial transport
• D. Chemical transport

Answer: (C)

Soil transport via glaciers occurs through glacial transport, which is the movement of soil and sediment by the action of glaciers. As glaciers advance and retreat, they pick up and carry large amounts of material, including soil, rocks, and other debris. This movement can shape the landscape significantly, leading to the creation of features like moraines and drumlins.

Glacial transport involves both the erosion of the land beneath the glacier and the deposition of the materials it carries as it melts or moves. This process differs from other forms of transport, such as wind erosion, which involves the movement of particles by wind, or gravity movement, which includes landslides and rockfalls where gravity causes materials to move downward. Chemical transport deals with the movement of soil constituents dissolved in water rather than physical movement of solid particles. These distinctions highlight the unique nature of glacial transport as a significant geological and environmental process.
