I was just atoms of silicon oxide until limestone grain invaded my privacy. It had borrowed me to the ground and put me into magma. I started to feel squashed up with the other silicon oxide atoms and were heated up from the heat. I started to feel different; like I was transforming like the Hulk but there were other atoms from other compounds meaning that we were being transformed into a metamorphic rock. All of a sudden, though, I started to cool and so did some of my other comrades as we rose closer to the surface. We were becoming igneous rocks. We had became sandstone and were happy with it.

We had started to roll over to the sea bed and fused with other with other silicon oxide atoms but as we went down into the ground, some of us became a sedimentary rock known as Chert.
