QUESTION 9

1. GigaPan 5.) General question - Does the glacier in this photo appear to be advancing or retreating?GigaPan 5.) General questionAdvancing: you can see it plowing up everything in its pathAdvancing: it's flowing downhillRetreating: the valley it sits in shows many features that indicate the glacier used to be larger and extend further downhill from its present position.Retreating: the valley downhill is V-shaped and shows no sign of more extensive glaciation.

QUESTION 21

1. Topographic map of Jackson, Michigan - Locate the landform called "Blue Ridge" on the map (first snapshot; also outlined in yellow on the Google Map), which happens to be made of sandy sediment (not till). Describe the most likely origin of this landform (text, page 615), and what is it therefore specifically called?This is an end moraine, deposited by a glacier.This is a medial moraine, in the middle of an active valley glacier.This is a lateral moraine, on the edge of a valley glacier.This is an esker, a deposit made by meltwater sorting glacial sediment.This is a kame, a mound-like deposit of till.This is a drumlin, a streamlined elliptical hill of till.This is a glacial outwash delta, where a stream fed into a standing body of water such as a lake.This is a cirque, a bowl-like depression carved by the upstream end of a valley glacier.

QUESTION 32

1. LiDAR map of Scandanavia - Explore the LiDAR image of a portion of Scandinavia. Try to find one of each of the following geomorphic features associated with continental glaciation. Take a screen shot of an example of each, then label key features of the image (annotate it), and submit (upload) those 5 images with your lab here:
   • glacial striations
   • terminal moraine
   • outwash delta
   • esker
   • kettles
   I recommend making one Word doc or PDF with all 5 images, and submit just that one "master" file containing all 5 answers.How to take a screen shot, if you're not familiar:Mac usersPC users
