Around the Rock cycle
to “Eye of the tiger” - the Rocky III theme tune
Da, da da da, da da da, da da daaaaa x 4
During this intro you do one of three things:
1) You could try to imagine three rocks, clad in bright
satin boxer’s gowns making their way down the smoky corridors towards the
classroom.
2) You could try to come up with some catchy lyrics to
fit the intro (if so - let me know!)
3) Alternatively you could go off and make a cup of tea.
Whatever you choose, just make sure you’re back by the time the piano chord cues your singing!
Rock fragments, washed out to sea
As the products of erosion
They’re deposited in layers you see
Add some shells and you should make limestone
The years go by, millions no less
And there’s an increase in pressure
Water’s squeezed out leaving salts solventless
They crystallise and the whole thing turns hard
Now we’ve, made sedimentary
It’s the slowest to form
It was made at the bottom of the oceans
But the movement of plates might force it up to the ground
Or send it on its way around – the rock cycle
There’s a change found underground
The result of heat or pressure
Heat from magma or as plates move around
Gaining strength, crystals form in clear bands
Now we’ve, made metamorphic
It is formed in the folds
As one plate buckles up over another
That lower plate is subducted and the rock’s melted down
And so it gets moved on around – the rock cycle
Molten rock, aka magma
Intruding up into the crust now
Here it cools real slow so big crystals grow
Randomly, interlocked is their form
And this rock type is igneous, it’s been formed in the fire
That is why you can find it near volcanoes
Here the crystals are small as it cools out on the ground
And so now we have come right around - the rock cycle
Da, da da da, da da da, da da daaaaa – Around the Rock Cycle! (x 5)
