Q. Which type of lake is formed by volcanic activities ?
✅ Correct Answer: (C)
Cladera lake
Explanation:
Caldera lakes are formed when a volcano erupts and its magma chamber empties, causing the ground above to collapse and form a large crater (caldera), which then fills with water.
- This is a common type of lake formed by volcanic activity.
Other options:
- Lagoon: coastal water body separated by sandbars or reefs.
- Freshwater lake: general term, not specific to volcanic origin.
- Karst lake: formed by dissolution of soluble rocks like limestone.
So, volcanic lakes are specifically caldera lakes — option (C).
