Rock Star Geology

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

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
