- Meanwhile, one million years later...
- I read about how you can change into something called a metamorphic rock through lots of heat and pressure. So over the 1 million years we've been down here we have formed into a metamorphic rock, a non-foliated one to be exact.
- We look so different! We are now white with streaks of clay and other minerals that have gotten inside of us during metamorphism! I think we should change our name for the last time to Mary the Marble!
- It's because we have been cemented and compacted together through thousands of years and formed a chemical sedimentary rock! To celebrate our change, let's name ourselves Larry the Limestone.
- Woah Sam, why are you getting so close to me?
- I'm just trying to compact together so we can make a sedimentary rock, Sally! This will also make us strong and we will look different too!
- A few Million years later...
- Hey Sam, you were right! We have changed in size and colour. I also do feel stronger. We are now a yellowish colour with small rocks, fossils and shells inside of us!
- See? I told you Sally!
- Meanwhile, 200,000 years later deep in the Earth's crust...
- Is it getting hotter in here? It seems like we have moved. Where are we? I wish I was back at the surface. There is so much heat and pressure down here
- I can feel it too!
- Ahh, it feels so nice to be cool.Oh no! It's getting super rainy and windy! Some parts of me are breaking apart! I think this is the process of weathering.
