Hey. My name is Chad. I'm an igneous rock that cooled from lava long ago. This... is my story.
I started off in magma, where I was in a sort of molten state. Eventually, a volcano spat me out as lava into the world above.
I've finally cooled off and have become an igneous rock. You know how much waiting goes into this process? Wait, I feel funny. Am I being eroded, or weathered, by this pool of water?
After being reduced to simple sediment, being painfully compacted and cemented, I've reached the stage of sedimentary rock. You know, I could totally live my life like this. Just relax, Chad. You've earned it.
Millions of years later... earthquakes and other natural disasters have forced our hero underground, where he is going through intense heat and pressure. Will he survive?
Yeah, he definitely will.
I'm back to the surface, better than ever, through the power of metamorphic activity! If you couldn't tell, I'm a metamorphic rock now. Nothing the world throws at me will phase me! I'll never change again!
Oh, you'll definitely change again, Chad. You'll always be changing.
