Question presented: Which of the following describes erosion?

Because the answer options are not provided in the data, I cannot analyze each listed choice. Instead, I will define erosion and explain how it is distinct from related concepts, so you can map the correct idea when you see the options.

Erosion is the process by which soil, rock, or other surface material is worn away and transported from one location to another by natural forces such as wind, water, ice, or gravity. It involves the removal and movement of material from its original place.

Key distinction: erosion vs. weathering. Weathering refers to the breakdown and alteration of rocks at or near the surface, without necessarily moving the material away. Erosion, in contrast, includes both the wearing away and the transportation of the resulting particles.

Common agents of erosion include:
- Water: rivers, rain runoff, waves
- Wind: sandblasting and aeolian transport
- Ice: glacial movement scouring and plucking
- Gravity: mass wasting processes like landslides can contribute to erosion by moving material downslope

Given the provided item, the statement that describes erosion would emphasize the removal and transport of material by natural forces (wind, water, ice, etc.), rather than merely breaking down rock in place.

If you encounter other options, they should reflect the idea that erosion involves movement of material away from the source, whereas a statement focusing only on wearing down in place or on chemical alteration without transport would describe weathering rather than erosion.
