Rocky the Rock
Текст Раскадровки
- Hi! My name is Rocky and I am a sedimentary rock. I am going to show you how I go from sedimentary, to metamorphic rock, and then to igneous rock.
- I was formed by other rocks breaking down into sediments in a process called weathering. Next, I moved to a new spot in a process called erosion. In my case, I was moved by a wind storm.
- I was then compacted and I made some new sediment friends. Then we became cemented together and are now best friends for life.
- You may ask, "Rocky, why do you look so different?", and my answer for you is that I changed! I am now a metamorphic rock!
- You may also be asking, "How did this happen?", and I'm about to tell you. I went through a process called regional metamorphism. This is where the tectonic plates of the Earth caused extreme heat and pressure which caused my parent rock to form into me.
- Now come with me as I change into an extrusive igneous rock.
- Wow! I think I'm a little sweaty! Most of it is gone now, but I was just reformed by lava aboveground. I am fine-grained because I didn't take long to solidify.
- I had fun taking you guys on my journey. I hope you learned something new!
