A picture of the Earth plates there. By the way, plates are actually slabs of rock that float on the mantle which is the layer under the crust. The earth structure goes like this - The inner core is the one that's in the middle of the earth and it's flaming hot( around 4,500 degrees). It's 2,500km wide and consists of mainly iron and nickel. the metal doesn't melt due to the pressure exerted on it. Surrounding it is the outer core, a great sea of liquid metal and again, it consists of nickel and iron. Followed next is the mantle , the layer below the crust( plates) and it's around 2,000 degrees, so hot that some stones melt to form magma. Imagine yourself getting engulf by the magma>.<> I am going to post a post about science tomorrow. So please do look forward to it
