EARTHQUAKES
Earthquakes are natural
disasters. “Natural disasters” mean disasters that happen naturally.
Volcanic eruptions and tsunamis are examples. Another example is
earthquakes. Here are the things that I’ll be teaching you (there are many
others I know):
How earthquakes
occur
Where do
earthquakes occur and
What to do during
an earthquake
How earthquakes occur
There are many ways earthquakes occur, but I will only tell you one. The
surface of the earth is made of many large pieces, or plates, that are
moving very slowly. Most of the earthquakes occur at the edges of these
plates, where they grate against each other. In some places, the rocks are
moving all the time, so small tremors happen almost everyday. In other
places, the rocks try to move past each other, but they get stuck. The
stress builds up for many years until finally, the rock snaps and a powerful
earthquake jolts the land.
