Fluvio glacial environments

How will all of this impact upon Fluvioglacial processes and Glacial sediment?

Fluvioglacial processes

Glacial sediment

How will this graph be relevant to fluvio glacial environments?

Glaciers and meltwater - homeworkHave a go at AS Glaciers question sheet 5

How would Glacial and Glaciofluvial deposits differ?

Glacial Till

Fluvioglacial outwash deposit

Glacial Deposits Fluvio-glacial Deposits (includes deposits once deposited by ice and re-deposited by meltwater)

Unstratified (difficult to identify layers)

Stratified (vertical layering due to seasonal variations in sediment accumulation)

Unsorted (random sorting as ice melts and deposits material regardless of size)

Sorted - larger rocks and boulders are deposited first as the meltwater looses energy.

Material is angular, from physical weathering and erosion (unaffected by water) and various shapes and sizes (boulders - rock flour)

Material is smooth and rounded (due to attrition), it is sorted and graded.

What do the graphs on Jokulhlaup’s show?

How might these processes help to create a unique landscape for fluvio-glacial areas?
