Explanation:

- Mass Wasting: This is the process by which soil, sand, regolith, and rock move downslope, typically due to gravity, especially after being loosened by rain. Thus, the movement of the boulder due to rain fits under mass wasting.

- Erosion: This involves the movement of rock and soil by natural forces like wind and water. While erosion can transport materials downhill, the specific movement of the boulder here is not primarily due to erosion.

- Weathering: This refers to the breakdown of rocks at the Earth's surface, due to factors like water, air, and temperature changes. This process could have weakened the boulder over time but isn't involved in the actual downhill movement.
