Answer 2

1: (A) Widespread volcanic eruption - (B) fissure eruption - (C) Deccan trap

2: (A) Andaman and Nicobar Islands - (B) Zone V - (C) Very high seismic vulnerability

3: (A) Mercalli scale - (B) Intensity - (C) I - XII

4: (A) Slow movements - (B) faulting - (C) Block Mountains

5: (A)  Philippines - (B)  Circum Pacific Belt  - (C) Mayon

6: (A)  Volcanic material (B)  - Volcanic bombs - (C) Solids

1. A volcanic eruption is a natural disaster from episodic earth movement. These can be fissure or cone types of eruptions. The Deccan Trap is the lava plateau formed from the lava spread erupted from volcanic fissure eruptions.
2. The entire stretch of Andaman and Nicobar Islands is in Zone V, which refers to a high seismic vulnerability that can also lead to tsunamis.
3. The Mercalli scale measures intensity of an earthquake by observing its effect on the Earth's surface, human life, and living, damages made to natural and man-made objects or structures. This scale marks an earthquake's intensity on a scale of I-XII.
4. Compressional horizontal orogenic movements are slow leads to faults or folds and forming rift valleys and block mountains.
5. The Circum Pacific Belt is a major volcanic belt and includes Japan's Fujiyama mountain, Mt. St. Helen in the USA, and mount Mayon in the Philippines.
6. Solid volcanic material erupting from a volcano falls like volcanic bombs.
