If two rocks have the same composition but one is more jointed and fractured, why is that rock likely to weather faster?

Answer and explanation

Correct answer: Because fractures increase pathways for weathering agents and the rock’s exposed surface area

Joints and fractures expose more rock surface and provide pathways for water and air to enter. This allows weathering to act on more of the rock, so option C is correct.
