The formation of soil occurs from both physical and chemical processes. Which of the following is not a physical process that creates soil?

Question

plant roots forcing their way into a crack of a rock, causing the rock to split
water freezing into rock depressions creating cracks that breaks down the rock
abrasions caused by friction of moving rocks against each other resulting in rocks breaking into fine particles
a rock slowly dissolving into a salty solution

Answer 1

The process that is not a physical process that creates soil is:

a rock slowly dissolving into a salty solution.

This process is a chemical weathering process, as it involves the chemical alteration of the rock material. The other options describe physical processes (mechanical weathering) that contribute to soil formation by breaking down rocks without changing their chemical composition.
