  1. Chemical weathering is acid rain. If it rains onto carbonate rocks e.g. limestone, they undergo a chemical reaction. This breaks down the rock.
  2. Biological weathering is animals and plants. Rabbits burrow under rocks which weakens them. Tree roots grow through rocks and weaken them. Weak rock breaks up easily.

Hope this helps x
