(2022·南京检测)Natural disasters take many different forms and can happen without warning. Earthquakes, floods, volcanoes, drought, typhoons and hurricanes are all natural disasters.

The survivors needed fresh water, food and shelters as well as medical help. People from all over the world gave money so that towns and villages could be rebuilt.

This is one cause of earthquakes, when one section of the earth collides with another. Scientists can predict where this might happen and the area between plates is called a fault line. However, earthquakes do not always happen on fault lines, which is why they are so dangerous and unpredictable.
Volcanoes happen where the earth's crust is thin—lava, dust and gases erupt from beneath the earth. They can rise into a massive cone shape—like a mountain and erupt, or they can be so violent that they just explode directly from the earth with no warning.
Hurricanes are extremely strong storms and often happen in the Caribbean. They cause high winds, huge waves, and heavy flooding and can cross hundreds of miles.
