Chapter 15: Eolian Processes and Arid Landscapes I. Introduction I.a. Wind=agent of geomorphic change, like water but less dense and can cause erosion, transportation, and deposition of materials I.a. Contributes to soil formation in distant places by bringing fine particles from regions where glaciers were active I.b. Spreads living organisms (mosses, liverworts, lichens) I.c. In desert environments (including polar regions), wind can create extensive sand seas and dunes b/c of lack of moisture and stabilizing vegetation I. The Work of Wind I.a. Eolian : refers to work of wind (erosion, transportation, and deposition) I.a. Ability to move materials is small compared to other agents like water and ice b/c of lower density, but still significant I.a. Importance of grain size: I.a.i. Intermediate-sized grains move most easily, they bounce along I.a.i. Large particles are heavier and need stronger winds I.a.i. Small particles are difficult to move b/c of mutual cohesiveness and presentation of a smooth (aerodynamic) surface to wind I.a.i.1. But finest dust, once aloft, can be carried from continent to continent I.a. Eolian Erosion I.a.i. Two principal wind-erosion processes that produce a variety of

    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.
