Which consequence primarily results when differential erosion isolates coastal rock formations?

💡 Explanation

Sea stacks result from differential erosion; wave action attacking weaker rock faster than stronger formations leads to isolation because wave refraction concentrates energy on headlands. Therefore, stacks form when weaker sections erode, rather than deposition, fjord formation or weathering alone.
