Question

what is the best explanation for the shape of the cliff in the diagram below? the minerals in rocks a and c erode faster than those in rock b the particles in rocks a and c are more firmly cemented than those in rock b rocks a and c are made of larger particles than rock b

Explanation:

The shape of the cliff indicates differential erosion. If rocks A and C erode faster than rock B, it would lead to the under - cutting and over - hanging shape shown. Firmer cementation in A and C (second option) would make them erode slower, not faster. Particle size relation in the third option doesn't directly explain the differential erosion causing the cliff shape as clearly as the first option.

Answer:

The minerals in rocks A and C erode faster than those in rock B
