There are many different glacial landforms created by glacial erosion, one of these landforms is U-shaped valleys or glacial troughs. This glacial landform has many distinct characteristics. One of these characteristics is that it has very steep valley sides caused by the glacier as it moves down the valley eroding the sides of the valley by the processes of abrasion and plucking. Abrasion is when the boulders and moraine carried by the glacier rubs and erodes the valley side as it physically moves down the valley. Plucking happens when the water in the glacier freezes inside of the cracks in...
snout of the glacier is melting, streams are flowing from the ice and therefore they carry material away. The streams tend to deposit the material as it is carried. Coarser and heavier material is deposited closer to the ice and the lighter and the finer material deposited further away from the ice. As the ice retreats the stops again, outwashed plains can develop on top of till.

Another piece of evidence that fluvio glacial action has occurred is the drumlins and drumlin fields in North Yorkshire near to ingelton falls this clearly shows that fluvio glacial action has occurred.
