  2. Vocabulary • Deposit/deposition: when eroded earth materials settle in a new place. • Erode/eroded/erosion: when weathered earth materials move due to wind, water or ice. • Flow: the movement of material downhill due to the force of gravity • Rapid: happening quickly, sometimes without warning • Weather/weathered/weathering: the breaking down of earth materials into smaller pieces by moving wind, water, and ice. • Delta : An area of deposited sediments caused when moving water meets a large body of water

  3. What are rapid changes? The term “rapidly” refers to changes that are visible within hours, days, or weeks. Examples of rapid changes may include: • Earthquake • Volcanoes • Hurricanes • Landslides • Floods • tornadoes

  4. Earthquakes: within minutes, pressure released from friction between tectonic plates can suddenly result in weathering through abrupt landslides of rock and crumbling rock formations. http://video.nationalgeographic.com/video/environment/environment-natural-disasters/earthquakes/earthquake-101/

  5. Hurricanes- these storms can cause severe beach erosion with their massive waves and forceful winds in a matter of hours. http://video.nationalgeographic.com/video/kids/forces-of-nature-kids/hurricanes-101-kids/

  6. Landslides: these occur when a large mass of soil or rock falls down a hill or mountainside due to the pull of gravity. They can also occur due to heavy rainfall over a period of time that causes supersaturated soil and gravity to quickly combine, forming a large flow of liquefied soil. http://video.nationalgeographic.com/video/environment/environment-natural-disasters/landslides-and-more/landslides/

  7. What are slow changes? Some changes to Earth’s surface happen slowly over time. The term “slowly” refers to changes that occur over decades or beyond the lifespan of a human being. Slow changes to Earth’s surface can be due to: • Winds • Running water • Rivers • Streams • Glacial movement
