Answer 2

Which one are you thinking?

Answer 3

Answer 4

Yeah apparently geological doesn't exist as a type of weathering.

Biological is basically plants/animals, and chemical is effectively oxidation or acidification, and mechanical is when processes like temperature are at play. I would say wind isn't a chemical, and definitely aligns more with heat as a means of erosion than with an animal.
