Which risk increases when differential erosion affects coastlines?

💡 Explanation

Increased coastal erosion at the base of sea stacks results in structural instability. This triggers gravity-induced toppling because undercutting weakens the base; therefore, sea stacks collapse more frequently rather than undergoing uniform erosion, which would only gradually shrink it.
