  1. Chapter 4 Erosion and Deposition Lesson 1 Water Erosion

  2. How does Moving Water Cause Erosion? Erosion is the process in which sediment that has been broken down through weathering is moved. Agents of Erosion are: • Water • Wind • Glacial (ice) • Waves Moving water is the major agent of the erosion that has shaped Earth’s land surfaces.

  3. Water Erosion Water causes erosion through the following ways: • Runoff • Stream and rivers • Ground water

  4. Water Erosion: Runoff Runoff is water that is moving over land, usually downhill. As water moves over the land it carries particles with it, as these particles and sediment are moved, the shape and surface of the land changes.

  5. Stream and River Formation Streams are formed from runoff flowing down hill. As the water flows and carries particles, different stream formations begin to form. • Rills and Gullies • Streams and rivers • Tributaries

  6. Rills and Gullies Rills and Gullies are small tiny grooves formed by running water down a hill. Rills are small and as they become bigger they become gullies.

  7. Streams and Rivers Gullies join together to form a larger channel called a stream. A stream is a channel in which water is constantly flowing down a slope. Eventually a stream can meet up with other streams and create larger channels of continues water called rivers.

  8. Water Erosion Water erosion is the movement of particles, sediment and such through the means of flowing water. Through erosion a river creates valleys, waterfalls, flood plains, meanders, and oxbow lakes.

  9. Water Deposition Deposition is the process in which sediment that has being moved lands and deposits itself somewhere new. Deposition creates landforms such as alluvial fans and deltas.

  10. Alluvial fans An alluvial fan is a wide, sloping deposit of sediment formed where a stream leaves a mountain range.

  11. Deltas A delta is the result of a landform that has being created from sediment deposited where a river flows into an ocean or lake.
