I do not know the exact question. But I can explain what weathering and erosion is to possibly help you.
Weathering- The process of wearing or being worn by long exposure to the atmosphere. (Usually rain and wind).
Erosion-The process of eroding or being eroded by wind, water, or other natural agents. (Such as acid rain over time slowly cutting into a rock and breaking it down into minerals).
