Chapter 17: Streams and Floods: The Geology of Running Water Earth: Portrait of a Planet, 3 rd edition, by Stephen Marshak Streamflow Stream runoff is an important geologic agent. Flowing water Erodes, transports, and deposits sediments. Sculpts landscapes. Transfers mass from continents to ocean basins. Earth: only planet in the solar system with flowing water. Without flowing water, Earth might resemble Mars.

    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.
