Chase's Rock Collection

Hi, it's me, Chase! This is my rock collection. My favorite rock in my collection is my dad's blue quartz arrowhead. He wanted it to be on display, so I put it with my rock collection.

One of my favorite types of rocks is amethyst. I have been reading about rock and learned that: *people used rocks as tools a long time ago
*diamonds are 10 times harder than any other rock
*sedimentary rocks have layers that have been formed by pressure over time

I'm still learning and always collecting! Pretty much everywhere I go I find a new rock!
