  • Fluvioglacial Landforms
    • Meltwater channels
      • Usually takes the form of a steep-sided (often dry) valley, carved into the landscape
      • Most commonly,it results from the overspill of a lake that builds up next to or in front of a glacier
    • Kames
      • Kames form a group of relatively minor features
      • They're largely made up on sand & gravel
      • There are three types
        • Kame terrace
          • The most extensive type of kame
          • Piles of deposited material left against the valley wall by meltwater streams
        • Kame delta
          • Forms when a stream deposits material on entering a marginal lake
        • Crevasse kame
          • when the ice melts, sediments are deposited on the valley floor to form small hummocks
    • Eskers
      • Eskers are long ridges of sand and gravel
      • They can be up to 30m high and often stretch for several kilometres
      • They run roughly parallel to the valley sides
      • They often appear at discontinuous hills because meltwater & postglacial rivers have eroded them away in places
    • Outwash plains
      • An extensive area of sands and gravels that forms in from of a glacier
      • Results from the "outwash"of sediment carried by meltwater and rivers
