869 - How do natural disasters like earthquakes and hurricanes occur?
There are two main types of natural disasters: those caused by the Earth and those caused by the weather.
Earthquakes: Earthquakes happen when there are movements or shifts in the Earth's outer layer, called the crust. This movement causes the ground to shake. It's like when you're on a bicycle and you hit a bump - it shakes you up. But with earthquakes, the bump is huge and can be very powerful.
Hurricanes: Hurricanes are powerful storms that form over warm ocean water. They happen when warm air rises, creating a low-pressure area. This creates a cycle where more air comes in and cools down, causing it to rain. It's a big, spinning storm that can be very strong and bring heavy rain and strong winds.
Think of it like this: Earthquakes are like the Earth's movements causing the ground to shake, and hurricanes are like big, spinning storms in the air.
