Which landform generally develops due to the retreat of a waterfall?
Answer and explanation
Correct answer: Deep valley or gorge
A waterfall retreats when turbulent water erodes and undercuts the softer rock at its base, causing the overhanging hard rock to collapse. Repeated undercutting and collapse move the waterfall upstream and leave a deep, narrow gorge in its former path. Therefore option C is correct. Sand dunes, sea stacks, and drumlins form through wind, marine, and glacial processes respectively.
