The correct answer is sewage, I just did this stuff in class last week.
Because it causes them to move, and so they weather that way. Buut the acid rain can leak into the rock and slowly break down the atoms, causing it to chemically weather faster. Also, just regular water/rain can wash away some covering sediment.
the nitrogen cycle involves decompisition. and the waste from the animals is then turned into nitrogen.
Idk bro sorry but I’m only in the 7th grade and don’t take biology
