Answer:
Your question is somewhat incomplete or is not well written, but even so, according to what is understood, it could tell you that the erosion of the surfaces affects with the increase of the vegetation of the surface.
Step-by-step explanation:
The plants when growing on eroded surfaces, or that suffered erosion, what they do is retain the eroded particulates and accumulate them, thus generating an increase in mounds.
A very clear example of this is the presence of sand dunes on the beaches that present vegetation, these sand dunes or dunes develop since the eroded sand particles are retained by the roots of the vegetation and slowing down the cycle of erosion.
