Q. Consider the following coastal landforms formed as a result of marine erosion:

1. Sea arches
2. Sea caves
3. Sea cliff
4. Sea stacks

Arrange the above landforms in the correct chronological order of their formation:
Answer: 2, 1, 4, 3
Notes: The correct sequence is: Sea caves are formed first by wave erosion, which then become larger, transforming into sea arches as openings develop. When arches collapse, sea stacks are left behind. Sea cliffs form as vertical slopes due to continuous erosion. Thus, the correct order is: 2 (Sea caves), 1 (Sea arches), 4 (Sea stacks), 3 (Sea cliff).
