Shane Bogin W00812443 Wild Rock Write-up Observations: The rock that I found to do my write-up about is the sedimentary rock coal. The chunk of coal that I found is dark grey, with small pieces of what appears to be sand and other rocks within it, some of which are shiny and others which do not reflect light at all. Looking at it closely, it seems to consist of a lot of different sized small grains cemented together into one soft rock. The coal that I gathered was very soft, breaking almost in half when I handled it, leading me to the realization that this specific piece of coal is bituminous coal or soft coal, which is why I was able to break it. Bituminous coal is the type of coal that is most commonly used for energy and is the third stage of coal formation. Looking closely at my rock, you can see that there is some slight layering, consisting of dark bands where it seems that two separate pieces of coal were compacted together.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
