I am very old now, but I haven't been metamorphic all my life.
I am Mr Gneiss Metamorphic. I know you might say where is the metamorphic rock on me. Its my head, I'm a rock head.
Let me tell the story......
This is me when I was a child, a bright, young sand sediment. (A chip off the old block!)
One day, I was feeling quite random. I had told the teacher and the teacher said "Don't worry about it. All sediments go through this." It felt like giant hands were compacting and cementing me and changing me into something different.....
I feel so weighed down!
When I came home I felt like a new man and I was! I was no longer a sediment, I was a sandstone sedimentary rock! (My mother was super impressed!)
A couple weeks later, on an excersion to study volcanos, some class mates and I got caught inside the volcano and the grumpy teacher didn't worry about saving us, instead he said "Too bad, it will be good for you."
