Layers Of The Earth

The earth is built in layers and the main ones are three
 The first one is the core and it's as hot as can be
 A lot of it is liquid, all the experts agree
 And that's the lowest layer of the earth
 The layer called the mantle is the next one to explore
 It's rocky but it's soft because of heat from the core
 It's kinda like a liquid but it's to thick to pour
 And that's the second layer of the earth
 The crust is at the top
 And it's mainly solid rock
 But it's made both separate plates
 With definite breaks
 Then it attached to get mostly
 They get very closely
 Between the crust and the mantle molten magma can flow
 But how does it rise up, you may be eager to know
 Well now it's time to introduce the star of our show to
 Tell you how volcanoes come from deep down in the earth
 Take it away Roxy!
