Question

Quizplus · Accepted Answer

Rocks reacting with organic acids from plants is a chemical weathering process, not a physical one. Physical weathering processes are those that break down rocks without changing their chemical composition, whereas chemical weathering processes involve changes to the chemical makeup of the rock. Frost wedging, salt crystallization, and tree root growth are all examples of physical weathering processes.
