  1. What is a sandbar that sticks up above the water and is connected to the shoreline?
    Barrier spit
  2. A long narrow island that forms parallel to the shoreline is called
    Barrier island
  3. What do continental glaciers do to the land they pass over?
    They flatten and smooth the land
  4. What do alpine glaciers do to the land they move through?
    They create sharp, rugged landscapes
  5. What are two (2) ways glaciers can move?
    SLIDE on land and FLOAT on water
  6. What is formed when waves cut completely through the rock in a sea cave?
    SEA ARCH
  7. What is a large hole in a weak rock near a sea cliff called?
    SEA CAVE
  8. A depression scooped out by the wind in the desert is called (type of deflation)?
    DEFLATION HOLLOW
  9. What is a rock surface consisting of pebbles and small broken rocks left behind after finer material has blown away called (type of deflation)?
    Desert Pavement
  10. What helps prevent wind erosion?
    Plants (roots)
  11. What is the most common type of landslide?
    SLUMP
  12. What is the steepest angle at which loose material will not slide down a slope?
    Angle of repose
  13. What type of glacier forms in a mountainous area?
    ALPINE GLACIER
  14. Dunes usually move in what direction?
    Same direction the wind is blowing
  15. What kind of pattern does a longshore current make?
    zigzag pattern
  16. What do waves make when they break rock into smaller pieces?
    SAND
  17. A landform created by offshore deposits which is made up of sand, gravel and shells is called
    SANDBAR
  18. What kind of landscape feature might have been carved by a glacier to form a waterfall?
    Hanging valley
  19. The wearing away of rock surfaces by other rock or sand is called
    ABRASION
  20. The skipping and bouncing of small particles in the direction that the wind is blowing is called
    SALTATION
  21. What is an example of a till deposit?
    MORAINE
  22. Why are some areas more affected by wind erosion than others?
    Some areas are not covered with plants/vegetation so the sediment/soil is easily blown away (i.e., deserts and shorelines)
  23. Describe how dunes form
    1st barriers slow down the wind which deposits sand. Next, sand builds up over time becoming a mound of sand which becomes a dune
  24. What is the difference between erosion and deposition?
    • Erosion is the removeal/wearing away of material/sediment
    • Deposition is the addition of sediment to an area
  25. A place where land and water meet is called
    SHORELINE
  26. Waves in a wave train are separated by a period of time called
    WAVE PERIOD
  27. The flow of a large amount of mud or rock and soil mixed with water is called
    MUDFLOW
  28. The slow downhill movement of rock material is called
    CREEP
  29. A group of loose rocks falling down a slope is called
    ROCK FALL
  30. The sudden rapid movement of rock and soil down a slope is called
    LANDSLIDE
  31. The blowing of millions of sharp sand grains that erod, smooth and polish rocks is called
    ABRASION
  32. Mounds of sand deposited by the wind are called
    DUNES
  33. The process in which wind blows away soil is called
    DEFLATION
  34. Identify the 3 step process of glacial formation
    • 1. snow builds up year after year
    • 2. top layer pushes down on lower layer (becomes more dense/compact)
    • 3. bottom layer turns to ice and movement begins
  35. The movement of any section of land down a slope is called
    MASS MOVEMENT
  36. What is an example of stratified drift?
    KETTLE
  37. Thick deposits of windblown, fine-graines sediment that are carried great distances are called
    LOESS
  38. Name the 5 types of mass movement
    • landslide
    • rock fall
    • mudflow
    • lahar
    • creep
  39. What is not a type of rapid mass movement?
    CREEP
  40. What is the steep side of a dune called?
    SLIP FACE
