Biological weathering can occur from mechanical force and chemical reactions such as through plants, bacteria, fungi, burrowing animals and living organisms
From the remarkable process of plates colliding and building mountains. They are only to be dismantled by mass wasting (weathering, erosion and transport).
Mechanical weathering is the breakdown of rocks into sediments by physical means.This type of weathering does not alter the chemical composition of rocks.
Chemical weathering is the process of transforming a rock’s composition through chemical reactions (by dissolving or converting them into other minerals)
