The Earth contains 3 layers Crust Magma (upper & lower mantle) Core
Crust The Earth is divided into 9 large plates and several smaller ones. These plates are called tectonic plates. These plates are not fixed, they float on top of mantle. Mantle Tectonic plates
Crust The crust is uneven. Some become continents and some become oceans. A G F B E D C

Movement of Tectonic Plates (earthquakes)
What are the natural phenomena in an earthquake? Volcanic eruptionCrater (lake)Tidal wave
What are the bad effects of an earthquake? Buildings and bridges were collapsed FirePeople were killed
What can we do? Scientists collect data about earthquakes. have fire drills. Build buildings which can minimize the bad effects of earthquake.
