C. The effects of acid from decaying animals
Precipitation (source of chemical weathering) Plant roots (source of chemical weathering) Freezing and thawing (source of mechanical weathering) Human activities (source of mechanical weathering)
the effects of acid from decaying animalsThe questions sounds like you were given choices which you didn't list. I would say "acid rain"
Hydrolysis is a source of chemical weathering, where minerals in rocks are broken down by the chemical reaction with water.

Oxidation is a source of chemical weathering. It occurs when minerals in rocks react with oxygen in the air or water, causing them to break down and weaken.
The abrasion of running water is a physical weathering process, not a source of chemical weathering. Chemical weathering is caused by reactions of rocks and minerals with substances like water, oxygen, and acids, which alter their composition over time.

The vegetation source of weathering is the organic acids released by plants as they decompose. These acids can break down minerals in rocks, leading to weathering processes such as chemical weathering. The roots of plants can also physically break apart rocks, contributing to mechanical weathering.

No. Chemical weathering is only when acid rain etc. is involved. I suppose you could call this 'natural weathering' but I'm not sure that is the correct term because it is simply water freezing and expanding.
