More About Mass Movement Worksheet Answer Key

Due Thurs. 11/19/15 by end of class! More About Mass Movement! Name: Answer Key You read PAGES 266 - 268, complete the following activities: Part 1: Chart of the geology and movement: Types of Mass Speed Slope Movement Landslide rapid steep Mudflow rapid gentle → steep Slump rapid steep Creep slow gentle → steep Part 2: Matching movement descriptions 1. landslide a. rock and soil suddenly slip down a slope in B one large mass b. rock and soil slide quickly down a steep 2. mudflow slope 3. slump c. rock and soil move very slowly downhill D d. a mixture of water, rock, and soil moves A rapidly downhill 4. creep C Part 3: Identification-write the type of mass movement (landslide, mudflow, slump, creep) example described 1. mudflow watery clay soil slides down a mountain 2. creep a telephone pole leans down hill 3. landslide/slump rock at the top of a cliff suddenly falls 4. landslide as you step on the mountain path, bits of rock and soil fall downhill 5. mudflow after a heavy rainfall, soil on a desert hill slides down 6. creep after many years, a gravestone on a hillside falls over 7. landslide during an earthquake, rock and soil move down a slope in one large mass 8. creep rock and soil suddenly slip downhill in one large mass All of these are caused by gravity
