  1. Wednesday, May 2 Attendance Collect Glacier Packet Glacier brainpop Finish Notes Lab # 45 Water Gaps

  2. Deposition – the dropping of sediment

  3. When sediments undergo pressure – they can turn into sedimentary rock.

  4. Little pieces of sediment can just stick together without a cement. Siltstone feels dirty – like a dusty rock.

  5. Big sediments need cement. Conglomerate

  6. Sorted – separated by size.

  7. Horizontal Sorting – when a river enters a lake

  8. Vertical Sorting – when sediment is dumped straight down.

  9. Landslides can dump sediment straight down into water.

  10. Graded Bedding- more than one vertical sorting.

  11. Deposition by gravity – unsorted, mix of angular fragments

  12. Deltas- triangular shaped land made from river sediment depositing where the river slows down.

  13. Alluvial Fan – deposit from mountain sediment onto land.

  14. Alluvial fan

  15. Waves deposit sediment on shore.

  16. Longshore Drift – waves moves the sand down the beach.

  17. Wind drops sand.

  18. Sand Dune Formation

  19. Melting Glaciers drop sediment.

  20. Glacial Erratics – giant rocks

  21. Glacial Deposits

  22. Drumlin – elongated hill

  23. Drumlins can tell direction.

  24. Do you recognize this place?

  25. Landscapes – how the land looks. Rochester, NY

  26. A different landscape Sedona, Arizona

  27. Mountains have a high relief.(Distance from top to bottom.) Adirondacks, NY

  28. Mt. Marcy – highest mountain in NY

  29. Plateaus-high relief – flat tops Allegheny Plateau, NY

  30. Colorado Plateau

  31. Ontario Lowlands (Plains)

  32. NYS Landscape Regions

  33. Humid landscapes are rounded. Genesee River in Letchworth State Park

  34. Arid (dry) landscapes are angular. Sedona, Arizona

  35. Young Stream

  36. Middle-aged streams

  37. Old-aged streams

  38. Oxbow Lakes – formed when a meander pinches itself off.

  39. Review of stream ages.

  40. Can you see the Genesee?
