1. A large mass of snow falling down the side of a mountain is an avalanche.
- An avalanche occurs when a large amount of snow on a mountain slope begins to slide down due to gravity. This can happen naturally or be triggered by factors such as snowfall, strong winds, or human activity. The mass of snow can be very large and can move at high speeds, causing potential danger to anyone in its path.

2. An extremely violent wind or storm is a hurricane.
- A hurricane is a tropical cyclone characterized by strong winds, heavy rainfall, and low atmospheric pressure. It forms over warm ocean waters and is classified based on its wind speed. Hurricanes can cause significant damage as they move across land, bringing strong winds, heavy rain, and storm surges, which can result in flooding.

3. A violent tropical storm in which the air goes round and round is a tornado.
- A tornado is a violent, rotating column of air that is formed in severe thunderstorms. It appears as a funnel-shaped cloud extending from the base of a thunderstorm to the ground. Tornadoes are known for their destructive power, capable of damaging structures and causing injuries or fatalities.

4. A shaking of the ground is an earthquake.
- An earthquake is a sudden release of energy in the Earth's crust, resulting in seismic waves. It occurs due to tectonic activity, such as the movement of plates, volcanic eruptions, or human-induced activity. Earthquakes vary in magnitude, and their effects can range from minor tremors to severe shaking, which can cause ground rupture and destruction of buildings.

5. A huge wave caused by an earthquake which flows onto land is a tsunami.
- A tsunami is a series of ocean waves triggered by large-scale disturbances of the ocean floor, typically associated with earthquakes occurring beneath or near the ocean. The displacement of water leads to the generation of powerful waves that can travel across entire ocean basins and cause significant destruction when they reach coastal areas.

6. A tall column of air spinning round very fast is a tornado.
- This question is repeated, but as mentioned earlier, a tall column of air spinning round very fast is indeed a tornado.
