Why Earthquakes Happen
An earthquake is when 2 plates rub together creating a strong force pushing on each other. When the 2 plates start moving again they grip onto each other extremely tight and this causes an earthquake.
There are about 20 plates along the surface of the earth that move continuously and slowly past each other. When 2 plates rub together it creates a strong force strong enough to shake the earth. As the plates move they put forces on themselves and each other. When the force is large enough, the crust is forced to break.
Underneath the Earth's surface lie tectonic plates. Sometimes they slide under one another or push up against each other, creating enormous stress. When they move again, they cause an earthquake. When the ground starts to crack it also starts to shake the ground.
The Earth is made up of four layers - the inner core, the outer core, the mantle and the crust. The mantle is about 1,750 miles thick, while the crust is only about 8 miles thick. When the tectonic plates slide apart, they create tremendous force. This force causes the earth to shake and ripple. Over 80 percent of the earthquakes happen in the pacific oceans in a place known as the ring of fires. Around 10,000 people die in earthquakes every year. Most of the deaths happenP when people are trapped in falling buildings. Scientists can use specials tools to record the strength of an earthquake. The Difference between the 20 plates that make up the earth and the tectonic plates is that the tectonic plates are very close to each other and can rub quite hard against each other.
To keep safe from an earthquake you have to get under a piece of strong furniture and cover yourself. If you are stuck in a building, quickly run outside to somewhere far away from the building.
I think that earthquakes should stop because very strong ones can kill loads of people and of people and in small earthquakes, it can kill animals and badly injure humans. I think that one day in the future scientists will invent aa way to stop earthquakes
Kia ora Pax, I liked how you explained the force of the tectonic plates but next time you should check your spelling for mistakes. I think this could help others when learning about the earth. Why did you choose to do this? From Aurelia
ReplyDeleteHi Pax your information report about earthquakes was great! It would be a good for anyone that wanted to learn about earthquakes and how they happen. From Thomas.
