Physical Geology 101 1 26. Erosion and Mass Wasting (p. 402-418) Erosion Where are two U.S. examples of where shoreline wave erosion is a major concern? 1. _____________________________ 2. _____________________________ Where is shoreline erosion also a problem at a large lake? ___________________ Weathering involves the breakdown of rock to form loose particles called regolith. Any process that involves the movement of this regolith from one location to another, and the abrasion of rocks hit by the regolith as it gets transported, is termed erosion . What 3 natural “elements” cause erosion? 1. _________________ 2. _________________ 3. _________________ What are the two characteristics of a flowing medium that play an important role in how effectively material gets transported? 1. _________________ and 2. _________________ The resultant types of fluid motion are called ______________ and _______________. Describe laminar flow: _____________________________ Is the flow speed high or low? ___________________________ Describe turbulent flow: ___________________________________ Is the flow speed high or low? ___________________________ Is turbulent flow more common in fluids with low or high viscosity? _________________ So which is more turbulent: water flow or wind gusts? ___________________ When pieces of regolith get lifted up off the ground and then bounce it along in small hops and jumps, we call this process ___________________.

    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.
