Answer:
B. Erosion occurs even when mountains are forming
D. When new mountains or plateaus form, the cycle starts over
Explanation:
The weathering, erosion, and deposition and three processes that are connected and depend on one another. They are one of the most responsible process for how the surface of the planet is shaped, as they influence the landscape constantly. The weathering is the process that breaks the rocks into smaller pieces, the erosion is the one that moves those pieces away, while the deposition is where the erosion stops and leaves the material that it has been moving. These processes are constantly active, even during the formation of a mountain, which results in slower picking up of elevation by the mountain range or plateau. The tendency of these three processes is to flatten the Earth's surface, but because of the geological activities they have never been able to do that.
