Which of the following erosional features is produced when waves break against a cliff face, undercutting it to form a horizontal notch that eventually collapses?

💡 Solution & Explanation

A wave-cut platform develops when continuous wave action erodes the base of a coastal cliff, creating a horizontal notch that eventually undermines the upper cliff until it collapses and leaves a flat rock bench. Landforms like sea stacks and tombolos represent different stages or types of coastal erosion and deposition respectively. Geomorphological studies of coastlines help in coastal zone management and erosion control.
