Investigating Glaciers

• What are the landforms glaciers create?
• Learning Objectives
• How do glaciers cause erosion?
• Is glacial erosion a slow or rapid process?

4
Glacial Grind

• How could we investigate glaciers using aluminum
  foil and ice?
• Remember to go with the flow!
• What would this process make real earth materials
  look like?

5
Glacial action thousands of years ago created
these deep grooves in rock. A moving mass of
glacial ice, perhaps a mile thick, dragged rocks
along beneath it to etch the grooves.
6
A foot bridge crosses a grooved depression
created during the last ice age. Glacial ice
dragged along rocks that scraped out the deep
grooves.

Common Misconceptions

• Glaciers only float in the water.
• Reality Glaciers actually sit on land and they
  grow faster than they melt.
• All glaciers are melting.
• Reality Glaciers are constantly changing,
  usually over long periods of time. Some are
  melting while some grow. Glaciers pick up rocks
  and soil, as well as drop off rocks and soil.
• Glaciers dont move.
• Reality Glaciers do move usually at a very slow
  pace.
• Glaciers are found only near the North Pole.
• Reality Glaciers are found in many areas,
  including near the North and South poles, and on
  the tops of mountains.
