Landform

The earth’s made up with four layers, the crust, the mantle, the inner core and the outer core.

There are millions of mountains and hills in the world. Some mountains were already on the earth surface, but there are some mountains that were formed by the tectonic- plates. The tectonic- plates tell us where the volcanoes are and which mountains were formed by tectonic-plates and that in which country they were in. The mountains form when you tectonic-plates rub together. Mostly all the disaster that happens on the crust for example volcanoes happens because of the Mantle and the core.

The mantle and the core are the cause of what happens on the crust. Because the core is very hot the rocks and the stones melt and becomes magma, the magma then rises up though the mantle and up on the crust and comes out as lava that’s what we call volcanoes and tha5t’s how volcanoes erupt.

Millions of years ago the earth was very different form the earth we see now. All the countries and islands we see now didn’t use to be like that. All the countries and island we see now like India, and Russia and all the countries use to all crash together like one big island. Because of the volcanoes and earthquakes all the countries and islands spread out and became the world we know now. In the future we think that the world we see will not be the same.
