Rock Identification lab II: 3/20/2021

 This week my classmates and I were able to further our understanding on igneous, sedimentary, and metamorphic rocks. After this activity I felt more comfortable in my ability to identify where different rocks fall in the rock cycle, along with what factors identify them. 

Lab:  We were given about 40 rocks and minerals to identify as shown in the photo below. With each rock I was able to pick out key characteristics. For example igneous rocks have crystals of various different sizes. This is due to the rate at which the rock cooled. Sedimentary rocks can often be rounded due to weathering and erosion. Metamorphic rocks are often flat as a result of heat and pressure. By using this knowledge and other physical attributes I was able to fill out the chart below, and name some of the rocks provided.

The Rock Cycle: 3/23/2021

I started my journey underground inside a volcano as magma, and it was very hot in there! One day I heard a loud cracking noise and started to feel pressure push me all the way to the top. Before I knew it I was pushed out of my home (that was some eviction notice). Once I was out of the volcano I got very cold. I sure didn't want to take my time freezing my edges off like the other intrusive rocks; so I decided to go the extrusive route and cool faster. Then I began the solidification process. I couldn't believe my eyes, I was full of holes and formed into igneous rock. Here is my first selfie, I am rough around the edges but still cute right?  As I tumbled down the hill I began cooling even more, and even formed some crystals! Not many though. Next I was squished and compacted by other rocks, I even lithified with someone else! But don't worry we got to know each other first. Once we became one our look changed. We were flat and just a tad bit shiny, you can thank my crys
