Work of Wind Transportation Transportation : Because wind is much less dense than water, it can transport only small particles, mainly fine sand sand and silt silt (clay is usually too cohesive). Particles move by either saltation saltation (sand) or suspension suspension (dust).

Wind-Driven Processes Only the finest particles ( dust ) stay suspended in air, most are carried along the ground through a process called saltation grains carried by the wind bounce along the ground When saltating sand encounters obstacles, it piles up to form dunes dunes move as sand is blown up the windward side and deposited on the leeward side resulting in cross bedding

    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.
