Glaciers

Glaciers

1. Bodies of ice formed from repeated snowfall

2. Alpine

   • Move downhill, carving out the valley into u-shaped ones
   • Rivers of ice

3. Continental

   • ice sheets
   • Move outwards from the centre
     • Usually to the coast

4. Large parts break off near the ocean is calving

   • These form icebergs

5. Striations are formed by the glacier grinding over the bedrock and plucking it

6. Glacial till

   • Unsorted and Unlayered sediment
   • Left behind when a glacier melts

7. Moraine

   • Large sediment deposits left by glaciers
   • Terminal moraines mark the furthest distance that the glacier reached

8. Glacial erratics

   • large boulders which dont fit the geology they are found in which have been transported by the glacier

9. Drumlin

   • Elongated hill of a glacial till
