Personal Response 5: Earthquakes

Hello everyone. Today I am going to talk about 'Earthquakes'.
Earthquakes can cause people to lose their homes, falling buildings, vehicles or trains and more.
People can protect themselves by hiding under a thick carpet, a huge table with good qualities, under a hard things and more.
I think that scientists can detect earthquakes. They use a machine to detect earthquakes. The name of the machine is called Seismograms.
Earthquakes occured in the recent China, Sichuan Earthquake, Japan, The United States Of America, Europe and more.
I think these countries have earthquakes because earthquakes are usually caused when rock underground suddenly breaks along a fault. This sudden release of energy causes the seismic waves that make the ground shake. When two blocks of rock or two plates are rubbing against each other, they stick a little. They don't just slide smoothly; the rocks catch on each other. The rocks are still pushing against each other, but not moving. After a while, the rocks break because of all the pressure that's built up. When the rocks break, the earthquake occurs. During the earthquake and afterward, the plates or blocks of rock start moving, and they continue to move until they get stuck again. The spot underground where the rock breaks is called the focus of the earthquake. The place right above the focus (on top of the ground) is called the epicenter of the earthquake.
I think sooner or later, Singapore will have an earthquake as most of the countries already had earthquakes and I also think that the earth is going to end soon because people have been burning things(I saw Indoneisia from my house and then i saw that there is fire there and there is alot of black(dirty) smoke rising up to the sky) , braking styrofoams, wasting resources, and many other more that can cause the ozone layer that protects the earth to be bigger and it will soon have a hole. By the way, it already have a very big hole.And I think that the earth is going to end very soon-20 more years?
Bye!
