Crust
Crust

In the earth's different crust
The thinnest part of the planet
It sustains all life, mantle, core
Crust does us right

Plate tectonics are the key
Changing things on land and sea
Volcanoes, earthquakes and such
Bring up all kinds of stuff
Without crust, we'd all die
Keeps all the magma down inside
It's really cool, now don't you see
Here comes the word, now sing with me

In the earth's different crust
The thinnest part of the planet
(Crust)
It sustains all life, mantle, core
Crust does us right
