It is approximately 1,800 miles thick.

Core The inner layer is called the core. What causes volcanoes to erupt? The Earths crust is made up of huge slabs called plates, which fit together analogous a jigsaw puzzle. These plates sometimes move. Between the Earths crust and the mantle is a heart a nd soul called magma which is made of rock a! nd gases. When deuce plates collide, one section slides on top of the other, the one down the stairs is pushed down. Magma is squeezed up between two plates. Did you know? Volcanoes are akin giant safety valves that kick the pressure that builds up indoors the Earth. Volcanic Eruptions As hygienic as the danger from the hot lava, an erupting volcano can induction are life baneful things....
