The earthquakes around the world
Earthquakes can sometimes make a lot of trouble and can kill people and can make
buildings topple on people. So that is sad. We are going to help the people that have
had earthquakes before. I know what it feels like. It is horrible! I've had it happened ONCE.
WHAT IS AN EARTHQUAKE Earthquakes happen when the moving of the tectonic plates that make up the surface of the earth moves apart or bump into each other, or slide under each other. This movement tears apart the surface of the earth, or crunches it up. Most often this just means it’s a little shaky for a few seconds and nothing very serious happens.
What causes an earthquake
Earthquakes are caused when the tension is released from the rocks in the earth’s crust and upper mantle. This tension is due to fiction between what scientists believe are large plates floating on magma on the earth’s surface. Sometimes earthquakes happened when the rocks in the earth’s crust bend and break. This causes shock waves to travel on the earth’s surface resulting in widespread destruction.
Study one specific earthquake
• Beijing – An earthquake toppled more than 1,000 houses and apartment
buildings in China’s southwest near the border with Myanmar killing at
least 25 people and injuring 250, the government said that it happened on the 15th June 2011. The government
also said that more than 25 fire fighters came and helped the people that mostly lost there children. Some
children lost their parents so they had to go to other people who
actually survived the earthquake.
