- 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
- Kame terrace
- 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
- Meltwater channels
