اسلاید 2: Earthquakes and How to survive ThemInter your Information

اسلاید 3: read1. The Earth is made up of three main layers: the crust, the mantle, and the core. The crust, the layer that you live on, is like the skin of an apple. It is very thin(from 6 to 30 kilometers) in comparison to the other two layers. It is broken into many pieces called plates . These plates float on the soft, plastic mantle below the crust. The core , which is at the center of the earth, consists of heavy metals and is about 4000º centigrade. Hot. Translation of this paragraphclick

اسلاید 4: 2. The plates of the crust move along smoothly but sometimes they stick together and create pressure. The pressure increases and the rock bends until it breaks. When this occurs, an earthquake is the result. Translation of this paragraph

اسلاید 5: 3. Earthquakes happen every day. Though millions of people may never experience an earthquake, it is a very common happening on this planet. So today, somewhere, an earthquake will occur. It may be so light that only special instruments can record its movement; it may shake houses, rattle windows, and change the place of small things. It may be strong enough to cause damage, injury, and death.Translation of this paragraph

اسلاید 6: 4. It is thought that about 700 shocks each year have this power when they occur in a populated area. Luckily. Most of these destructive earthquakes occur in less populated places.Translation of this paragraph

اسلاید 7: 5. Since a large number of the world`s earthquakes each year occur along the Pacific Ocean, this is the most probable area for today`s earthquakes. But it could hit any place because no area is entirely free of earthquakes.Translation of this paragraph

اسلاید 8: 6. Saying that an earthquake is going to happen today is not really predicting earthquakes. So far, they cannot be predicted, but anyone, on any day could say this and it would be true. This is because several million earthquakes occur each year. So, thousands occur each day, although most are too small to be located. The problem is in finding the exact area and when a strong shock will happen.Translation of this paragraph
