It can be if it's from an acid or similar chemical. If it's due to a rubbing action, though (like those novelty soaps with the grainy texture), it's mechanical. Also, "weathering" is an odd term to use with a living organism. It's more akin to cleaning.
Which of the following is an example of chemical weathering?
An example of weathering in the Edwards Plateau could be the process of exfoliation, where outer layers of rock gradually peel away due to expansion and contraction caused by changes in temperature. This can result in large slabs of rock breaking off and forming distinctive domed landforms in the region.
Exfoliation is a form of physical weathering where outer layers of rock gradually peel away due to pressure release. This process is often influenced by factors like temperature changes and erosion, leading to the expansion and consequent detachment of rock layers.
No, splits in a rock due to tree roots is an example of physical weathering or biological weathering, not chemical weathering. Chemical weathering involves the breakdown of rocks through chemical processes like dissolution, oxidation, or hydrolysis.
An example of a non-physical weathering process is chemical weathering, where rocks are broken down by chemical reactions rather than physical forces like temperature changes or abrasion.
Exfoliation of granite occurs due to weathering processes like thermal expansion and contraction, which lead to the outer layers of the rock peeling off. This process is also influenced by the presence of joints and fractures in the granite, allowing for easier separation of layers. Additionally, chemical weathering can weaken the bonds in the rock, contributing to exfoliation.

Therew is only to types of weathering in my knowledge and they are Mechanical and Chemical (in scientific term). Mechanical is also know as physical.

Frost wedging & exfoliation are common terms associated with mechanical weathering.

A type of Chemical weathering that happens when water interacts with minerals.
In some case chemical weathering can cause this (where new crystals form from old ones but where the volume of the new crystals is not the same as the original). In other cases the weathering process is temperature driven by water entering the porous layer of a weathering rock and freezing. This can split the rock parallel to the surface, giving it exfoliation layers. Some texts also imply that exfoliation domes are produced by by removal of vertical pressure relieving paleo stresses in the rock, this however would not be a weathering process.
