Unformatted text preview: joints. Joints are a series of parallel fractures in the mountain which can alter the terrain. As the glacier freezes and thaws, it’s deposition of sediment, rocks, and minerals creates morrains. Morrains are large piles of deposited materials which prevent a river or stream from flowing in a particular direction. These morrains can vastly alter the terrain of an area. Mass wasting events can also alter the terrain of an area. For example, a rockslide or mudslide can create new depositions of material, altering the local geological landscape. In Innsbruck, we see evidence of such events due to the protective barriers located at the top of the mountain. During the last ice age, the sheet of ice which covered Innsbruck can be seen in the shapes of the mountains. Rounded mountains were covered with ice, while jagged ones remained above the surface and exposed to erosional elements....
