determining the bulk density was the Cinnabar soil. It had a lower bulk density compared to the other soils, which indicates that the Cinnabar had a higher percentage of clay and silt than most of the other soils. Since the Cinnabar was not one of the soils that was textured the bulk density was not able to be compared to the actual percentage of clay in the soil.

    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.
