Guided Notes Erosion and Deposition Erosion is the _____________________________ of rock particles from a location. Typically caused by __________________, _________________, ___________________, or __________________. Water Erosion Water sources such as rivers, streams, ocean tides, and run off can move rock particles away. • • • Moving water is one of the most powerful agents of erosion. Erosion by water can have__________________________ results. Rill erosion develops when ____________________ water cuts small channels into the side of a slope. Erosion by Water: Rivers • • Rivers and streams carry_____________________. As the sediment moves mechanical_________________________ occurs. Through water erosion, rivers create __________________, flood plains, and valleys. Erosion by Water: Waves • • Waves- waves ________________________________ the coasts by transporting sand. While the sand is moved, _____________________ weathering occurs. Waves create sea _________________, caves, arch, and wave-cut cliffs. Erosion by Water: Run-Off • As water from precipitation (rain, snow, etc.) moves over the land, it carries particles with it. The moving water is called runoff. • Runoff creates rills and gullies. Wind Erosion Sometimes the wind can move rock particles away: this can lead to dust storms! Fine particles are carried through air. Medium-sized particles skip or bounce. Larger particles slide or roll. Wind ____________________creates dust storms, hoodoos, and arches Ice Erosion (Glacier Erosion) As a glacier ________________ over the land, it picks up rocks in a process called __________________. Ice erosion creates: U-shaped valleys, glacial lakes, moraines, drumlins, and kettle lakes Erosion by Gravity • ___________________ causes sediment to move downhill. It creates: landslides, mudflows, and creeps Weathering and Erosion work together continuously to wear down and carry away the rocks at the Earth’s surface!!!!! Deposition • • Deposition is the process in which _____________________ laid down in _____________ locations. Caused by water, wind, ice, and gravity. Types of Deposition Wind Creates Sand Dune Water Waves and Rivers Beaches Delta Ice Moraine Gravity Landslides, Slumps, creep Picture
