How are volcanoes classified based on the periodicity of their eruptions?
उत्तर
Based on the periodicity of eruptions, volcanoes are classified into
- Active Volcano:
Active volcanoes are those which constantly eject volcanic lava, gases and fragmented materials Eg: Mount St. Helens in the United States.
- Dormant Volcano:
- Volcanoes that do not show any sign of volcanic activity for a long period of time are known as dormant volcanoes.
- Sometimes there may be a sudden explosion which may cause unimaginable loss to life and property.
- Eg: Mt. Fuji, Japan
- Extinct or Dead Volcano:
When a volcano permanently stops its volcanic activity, then it is called an extinct or dead volcano. Eg: Mt. Kilimanjaro, Tanzania.
