Which rock will it stay Can you figure it out
From one rock to another on a recycling route
But never in a hurry On Earth's "takin' its time clock" (they don't stop)
They keep changin' rearrangin' that's the cycle of a rock
We'll start this blues song With an igneous rock
Which gets its beginning In Earth's big melting pot
Belched from the big magma flow Into the bedrock or on top
Through a crack called a volcano Out comes an igneous rock
Then the Earth's elements won't leave the poor rock alone
Ice, wind and water They break up the stone
Into tiny, tiny pieces we call sediment (the dirt begins)
They get all stuck together....THAT DARNED ROCK'S CHANGED AGAIN!
Just when you think the sedimentary rock is finished
The plates keep tecton-in' and the rock gets all squished
Or changed by pressure Or hot from magma way too close
Bands form from rock rearrangin' --THEY GET ALL METAMORPHOSED!
But if you think this is the end You're not thinkin' too clear
'Cause a rock won't stop no it won't stop here
It gets weathered, squished or melted Baby, in this you can take stock
Changin' forever and ever....that's the cycle of a rock
Instrumental
When men first discovered this It came as a shock
It was thought only one identity for each kind of rock
Like a sort of registration, baby given at birth (but no sir!)
But now we're gettin' a handle on our dynamic earth
Changin' forever and ever that's the cycle of a rock
We learn earth's deepest, dark secrets from the voices in the rocks
Changin' forever and ever that's the cycle of a rock
