Glacial Processes

Glacial Processes There are many different gelid landforms created by crisp 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 expressions 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 the individual rocks on the valley side then(prenominal) the water freezes and as the glacier moves the rock is plucked or tear from the valley side producing the steep side to the valley. The valley excessively has wide flat floors caused by ice movement aided by large volumes of melt water and moraine has greater caustic power than that of rivers. This results in the wide floors.
