प्रश्न
Give a geographical reason:
Extinct conical volcanoes often form crater lakes.
कारण सांगा
उत्तर
Extinct conical volcanoes often form crater lakes because -
- An extinct volcano had no volcanic eruption for at least 10,000 years and is not expected to erupt again in the future.
- After the eruption, a large and deep depression remains in that area. Smaller depressions are called craters.
- This crater eventually gets filled with water and crater lakes are formed.
- The water may come from precipitation, groundwater circulation, or melted ice.
