JUST THE FACTS, PLEASE:
NOW THE ANALYSIS:
CIRCLE ONE EXPLAIN YOUR CHOICE SORTED UNSORTED
Therefore, it seems that GLACIAL ACTIVITY is the only erosion agent capable of creating moraines!
- A major factor in glacial erosion is the weight of the overlying ice pushing down on the rocks which are frozen into the base of the glacier. The greater the weight, the more effective the erosion.
- Study the third (far right) diagram above carefully, paying attention to how the thickness of the ice in the same glacier varies with topography (level of the land it is on). Why would you expect faster erosion in the former valley bottoms or on the former hill tops (pick one and explain)?
- Draw arrows on the Michigan Map showing the direction of the ice motion for each of the 5 major ice lobes found on this map. [The Lake Erie lobe arrow is already drawn as an example.]
