For all mountains, ocean floor, will give it shape
It's only 5 to 40 km in length
This is the outer part, the crust it is its name
You'd think it wider on it's own well it ain't
And geologists will study rock
Constantly changing, forces affect surface
Constructive opposite destructive
It's building up or breaking down
And we think Earth's insides something
Four different layers of stacked, seismic waves tell us that
The crust is rock, soil too and it's like the outer one
It ranges 5 to 40 km long
And dive down the mantle has a job, convection is going on
Lithosphere stone, asthenosphere is weak and soft
Outer core is like a wave of metal mush
Oh, baby nickel, iron, liquid gel
And we do think that inner's holding on to atoms
Squeezing tight a solid shell
And as we move lower rock melts and it bends
Magnesium, iron, silicon, oxygen
Convection currents churning hot-rises, cold-down
Asthenosphere pushes lithosphere along
And geologists will study rock
Constantly changing, forces affect surface
Constructive opposite destructive

And we do think that inner's holding on to atoms
Squeezing tight a solid shell
For all inside the Earth's made of two cores
Outer is made of all iron, nickel metal
And always stays molten when pressure is incredible
But changing the rule inner is a solid ball
Outer core is like a wave of metal mush
Oh, baby nickel, iron, liquid gel
And we do think that inner's holding on to atoms
Squeezing tight a solid shell
