Study Notes
- Glaciers are bodies of ice formed from repeated snowfall, moving slowly downhill due to gravity.
- There are two main types of glaciers: alpine glaciers found in mountains and continental glaciers covering entire land masses.
- Alpine glaciers resemble rivers of ice flowing downhill while continental glaciers, like Antarctica and Greenland, move outward from the center.
- When glaciers reach the ocean, large chunks break off in a process known as calving, which is happening at an accelerated rate due to climate change.
- Glaciers impact the landscape by grinding rock to create U-shaped valleys, leaving behind striations that indicate the ice's movement direction.
- Glacial till, unsorted sediment deposited by melting glaciers, forms moraines like terminal moraines marking the furthest extent of glacier travel.
- Glaciers can move large boulders called glacial erratics and create drumlins, elongated hills indicating the direction of ice flow.
- The melting of glaciers leads to the formation of kettles and kettle lakes, along with outwash plains from meltwater runoff.
