Erosion- the process in which weathered particles are picked up and moved from one place to another. Deposition- process in which sediment is placed in a new location or deposited (part of erosion. GRAVITY is important for both erosion and deposition. Gravity causes water to move downwards, carrying and depositing sediment as it flows. Gravity can pull huge masses of ice slowly down mountain valleys. Gravity causes dust carried by the wind to fall to Earth. Erosion of weathered rock by the movement of water, wind, and ice. Mass Wasting - the downhill movement of masses of rock and soil. (it can occur suddenly or gradually) Landslide- fast movement of rock and soil. Mudflow - movement of mud or soil. slides/falls- movement of rock Rockfall and rockslides. Mudflow - movement of mud/soil Debris- mixture of rock, soil, and plants Debris is common in high mountains with steep slopes. Major type of mass wasting of debris is a mudflow. Contain large amount of water. Mudflows happen: In mountain canyons and valleys after heavy rains. Active volcanoes Two main types of mass wasting on hilly land -less dramatic than rockslides/mudflow Slump and creep.

    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.
