Chapter 9 Weathering and Soils 2 CHAPTER 9:1 THE DIRT ON WEATHERING PG . 244 KEY POINTS: Weathering breaks down and alters rocks and minerals at or near Earth’s surface. Weathering can slowly degrade historical monuments and buildings. There are three types of weathering; physical, chemical, and biological. Regolith is the physically, chemically, and/or biologically weathered remains of rock. Soils are composed of regolith, water, air, and organic materials. Commonplace actions are similar to the simple geologic processes that slowly wear down rocks at or near Earth’s surface.

    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.
