Which weather process involves physical forces but not chemical reactions or dissolving of mineral

A. solution

B. carbonation

C. abrasion

D. hydration

The correct answer is option C, abrasion

Reason -

Abrasion is a mechanical weathering or scrapping process in which a big rock is broken into smaller rocks when the rock grinds against another rocks or sediment. It usually occurs due to the friction between the rocks when they are carried by wind, waves, water or any other natural or artificial force. While in other processes i. e solution, carbonation and hydration some form of chemical reaction takes place to break the rock.

Your answer is C. Abrasion. Abrasion is a mechanical weathering, which uses physical forces to break down rocks without changing the chemical composition. The other answers are examples of chemical weathering.
