11.Fluvioglacial Processes and Landforms

1. Kame

   • mounds of sands and gravel found on the valley floor, form by debris falling through crevasses and deposited once ice has melted

2. Eskers

   • long winding ridges of sand and gravel that run in the same direction as the glacier
   • deposited by meltwater streams flowing in tunnels underneath the glacier, sorted and stratified sediement

3. Kame Terrace

   • piles of deposits left against the valley floor by meltwater streams that run between the glacier
   • look like lateral moraine but are sorted into layers, so will have heavier rocks at the bottom

4. Outwash Plain

   • layer of gravel, sand, and clay that forms indent of where the snout of the melting glacier used to be
   • Gravel gets dropped first, then sand and clay

5. Proglacial lakes

   • form infront of glaciers, can be dammed by terminal moraine

6. Delta Kame

   • Meltwater streams deposit their sediment
