Weathering and erosion
Explanation:
Weathering and erosion are the processes that would be partially responsible for the change in the landmasses. Since the image shows movement of continents to their current positions, their surfaces would have been sculpted by the agents of denudation through its 250mya history.
- Denudation is the gradual process of lowering and leveling of the earth surface by breaking and wearing away of such surfaces.
- The agents of denudation are wind, running water, ice and waves.
- Denudation is a constant process that the earth undergoes from time to time.
