Weathering is the breakdown of rocks, soils, and minerals through physical or chemical processes. It occurs in place, meaning the material doesn't move.

Erosion is the transportation of weathered material by wind, water, ice, or gravity. It involves the movement of material from one location to another.

On steep slopes, gravity plays a significant role in erosion. The force of gravity causes weathered material to move downslope, leading to rapid erosion. This is evident in the formation of landslides, rockfalls, and soil creep.

While weathering does occur on steep slopes, its effects are often overshadowed by the dominant force of erosion. The weathered material is quickly removed by erosion before it can accumulate significantly.

In summary:

* Weathering breaks down rock, but erosion moves it.

* Steep slopes favor erosion due to the influence of gravity.

* Weathering still occurs but its effects are less prominent compared to erosion on steep slopes.
