Depositionfeatures

  1. 2. Review What’s going to happen to the ball? Why? Erosion features – Add a feature to the diagram on the board and explain it as you go.
  2. 3. Lesson Objectives <ul><li>To be able to define and describe different coastal depositional features . </li></ul><ul><li>To be able to explain how these coastal features have been created by deposition. </li></ul><ul><li>WHY? So next time you’re lying on a beach getting a tan, you’ll understand why you’re lying on sand rather than rocks! </li></ul>
  3. 4. Beach – Holderness, Yorkshire
  4. 5. Beaches <ul><li>A collected body of material (sand, shingle etc.) that has built up between the high and low tide mark. </li></ul>
  5. 6. Spit - Spurn Head, Humber Estuary
  6. 7. Spits <ul><li>Spits are long narrow ridges of sand and shingle which project from the coastline into the sea. </li></ul>
  7. 8. Bar - Slapton Sands, Devon
  8. 9. Bars <ul><li>A collected body of material (sand, shingle etc.) that connects two sides of a bay, joining two headlands. </li></ul>
  9. 10. Tombolo – Chesil Beach, Dorset
  10. 11. Tombolos. <ul><li>A collected body of material (sand, shingle etc.) that connects land to an offshore island </li></ul>
  11. 12. Beaches
  12. 13. How do Beaches Form? <ul><li>Beaches are one of the most common features of a coastline. Beaches are made up of eroded material that has been transported from elsewhere and deposited here by the sea. </li></ul><ul><li>Constructive waves help to build up beaches. The type of material found on a beach (i.e. sand or shingle) is influenced by the geology of the area and wave energy. </li></ul><ul><li>Material from long-shore drift builds up on the beach </li></ul>Task: Write in your own words
  13. 14. Spits
  14. 15. How do spits form?
  15. 16. How do Bars Form? <ul><li>These form in the same way as a spit initially but bars are created where a spit grows across a bay, joining two headlands. Behind the bar, a lagoon is created, where water has been trapped and the lagoon may gradually be infilled as a salt marsh develops due to it being a low energy zone, which encourages deposition. </li></ul>
  16. 17. Bars
  17. 18. How do tombolos form? <ul><li>Tombolos are formed where a spit continues to grow outwards joining land to an offshore island. </li></ul>
  18. 19. Tombolos
  19. 20. Homework <ul><li>Locate and find pictures of a: </li></ul><ul><li>Beach </li></ul><ul><li>Spit </li></ul><ul><li>Bar </li></ul><ul><li>Tombolo </li></ul><ul><li>Label and stick them in your exercise books </li></ul>
