The answer is E. Explosion.
A flood is a large amount of water that covers an area that is usually dry. A hurricane is a large storm with strong winds that forms over warm ocean waters. An avalanche is a large mass of snow, ice, and rock that slides down a mountain. An earthquake is a sudden movement of the Earth’s crust.
An explosion is a sudden release of energy that causes a loud noise and a shock wave. Explosions can be caused by a variety of things, including chemical reactions, nuclear reactions, and the detonation of explosives.
The other four options are all natural disasters. Explosions are not typically considered natural disasters, as they are usually caused by human activity.
