Types of Rocks

Yeah, so you want to be a rock star, huh? I got you. Look:

Oh, you like rocks like Dwayne Johnson?
There's three different types, let me show you each option.
The first type is igneous; they were first on the planet,
And the newest rocks being created right now, understand it.
They form when magma and lava cool,
So I wouldn't touch before they do, if I was you.
Think you might forget? Here's a quick reminder,
In Latin, ignis means “fire.” 
Next up are sedimentary rocks, we can't stop.
Their formation starts with the weathering of another rock.
Weathering means the wearing down.
Erosion is when weathered rocks are moved by wind and water, all around.
Then they are deposited like money in the bank,
Meaning they stop moving like a broken tank.
In time, the sediments form layers,
And stick together as rocks like two of my favorite players.
Different rocks are formed from different sediments,
Depending on where they get deposited, is it evident?
A metamorphic rock forms from an existing rock
That gets buried very deep, under pressure and where it's very hot.
The pressure and the heat are very high.
But the rock doesn't melt, it morphs, I wouldn't lie.
Morph means change, if you didn't know.
Now morph into a rock star, let's go!

So you want to be a rock star and get hype?
There's three different rocks, better know every type.
I'm talking about igneous, sedimentary and metamorphic.
Study until you get it, don't forfeit,
And you can be a rock star.

And you can be a rock star!

So you want to be a rock star and get hype,
Here's a few clues to figure out a rock's type.
Igneous rocks often have crystals, but if you're not seeing them,
It could be obsidian.
That's one example of an igneous rock with the crystals missing,
They may look glass-like, shiny and glisten.
Usually they're not layered, but I suggest
You look for gas bubbles trapped during the cooling process.
Sedimentary rocks can be layered or striped,
And grains of the sediments can look glued together tight.
They are soft, most of the time,
And can crumble easily like cookies of your favorite kind.
That's not every clue, believe I got more.
Usually the rock that might contain a fossil from a dinosaur.
Imagine digging though many sedimentary rocks,
Crack one and see the horn of a Triceratops!
Last on the list you can pick,
Are the rocks we know as metamorphic.
They may have mineral grains in alignment,
That means lined up, before you look it up and find it.
They may have ribbon-like layers of minerals called bands,
Like gneiss, have you held it in your hands?
Other metamorphic rocks are schist and slate.
Slate is what they used to make blackboards back in the day.
