Erosion & Deposition by Gravity, Ice, Wind Notes

Erosion & Deposition by Gravity, Ice, Wind Notes Name: Claire Gravity: Complete the following chart with a brief definition of each type of mass movement and then cut and paste the appropriate picture that shows each type in the space provided. Type Definition Diagram Landslide Landslide happens when a lot of rock and soil moves really fast and suddenly down a slope. Most common landslide is a slump. (block of material moves downhill along curved surface) rectangular block on a slope with a curved surface, partially slid down Rockfall Rock fall happens when rocks fall down a steep slope because they were loose. The rocks can be in different sizes and gravity can cause the rocks above the road to fall. (slopes found on sides of roads through hills) cliff face with several rocks of various sizes fallen at the bottom Mudflow Mudflow is a fast movement of big amounts of mud. It happens when lots of water mixes with soil and rock, the water makes the mud flow downhill very quickly because its slippery. mass of mud flowing down a slope, with a thick consistency and uneven surface Lahar Lahars are volcanic eruptions that produce dangerous mud flows. Snow and ice can form melt on a snowy peak because of volcanic eruptions, water mixes with the soil and ash and produces hot flow that goes downhill. volcano with a flow of mud and debris moving down its side Creep Creep is a very slow movement of material down a hill. They can move large amounts of material over time, a long time. gentle slope with tilted trees and a slightly curved surface, indicating slow movement
