Two that are frequently linked toone another are earthquakes and tsunamis. Both of them can cause a great amount of devastation when theyhit. However, tsunamis are the direct result of earthquakes and cannot happen without them.The Earth has three main parts. They are the crust, the mantle, and the core. The crust is the outer layer ofthe Earth. It is not a single piece of land. Instead, it is comprised of a number of plates. There are a fewenormous plates and many smaller ones. These plates essentially rest upon the mantle, which is fluid. As aresult, the plates are in constant - yet slow - motion. The plates may move away from or towards other plates.In some cases, they collide violently with the plates adjoining them. The movement of the plates causestension in the rock. Over a long time, this tension may build up. When it is released, an earthquake happens.Tens of thousands of earthquakes happen every year. The vast majority are so small that only scientificinstruments can perceive them. Others are powerful enough that people can feel them, yet they cause littleharm or damage. More powerful earthquakes, however, can cause buildings, bridges, and other structures tocollapse. They may additionally injure and skill thousands of people and might even cause the land to changeit appearance.Since most of the Earth's surface is water, numerous earthquakes happen beneath the planet's oceans.Underwater earthquakes cause the seafloor to move. This results in the displacement of water in the ocean.When this occurs, atsunamimay form. This is a wave that forms on the surface and moves in all directionsfrom the place where the earthquake happened. Atsunamimoves extremely quickly and can travel thousnadsof kilometres. As it approaches land, the water near the coast gets sucked out to sea. This causes thetsunamisto increase in height. Minutes later, thetsunamiarrives. A large tsunami - one more than ten meters in height -can travel far inland. As it does that, it can flood the land, destroy human settlements, and kill large numbersof people.
