Glacial Processes

Glacial Processes There are many different pungent landforms created by north-polar erosion, one of these landforms is U-shaped vales or flash-frozen troughs. This glacial landform has many distinct characteristics. One of these characteristics is that it has very steep vale fonts caused by the glacier as it moves down the vale eroding the positionings 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 co untenance of the cracks in the individual rocks on the valley side then(prenominal) the water freezes and as the glacier moves the rock is plucked or mangled from the valley side producing the steep side to the valley. The valley withal has bulky flat floors caused by ice movement assisted by large volumes of melt water and moraine has greater corrosive spring than that of rivers. This results in the wide floors.
