Why can a sea cliff retreat rapidly?
Answer and explanation
Correct answer: Due to constant wave attack and notch erosion at the base
The governing concept is marine erosion at the cliff foot. Repeated wave impact, hydraulic pressure, and abrasion excavate a wave-cut notch at the base. The unsupported material above becomes unstable, collapses, and leaves the cliff face farther inland; repeated cycles produce rapid retreat. Thus option A is correct. Wind deposition, glacial salt deposition, and delta growth are not the direct causes of sea-cliff retreat.
