Folding Ductile deformation of rocks results in folding. o Open Google Earth Pro and navigate to Dent de Morcles, Switzerland. Investigate the area - zooming in and out between ~12 km and 3 km eye altitude. The image below is of the west-facing cliff face. o Below create a sketch of the image above (it is a cross-section, because it is a cliff face). Use arrows to indicate the direction of stress that created these features. • How do you explain the lines on the cliff face? (Plausibility) 1 • How do you think these rocks were deposited originally? Use a sketch in your explanation if it is helpful. (Plausibility) Click or tap here to enter text. • In what ways have they changed since deposition? (Plausibility) Click or tap here to enter text. • What sort of plate tectonic environment do you think created this feature? (Plausibility) Click or tap here to enter text. • Do you think this these features formed deep (high pressure/high temperature), shallow (low pressure/low temperature)? Explain your reasoning? (Plausibility) Click or tap here to enter text. 2 Step 2. Faulting Fracture of rocks results in faulting. o Open Google Earth Pro and navigate to Tent Rocks, New Mexico. Investigate the area to the NE of the marker, by zooming in and out between ~5 and ~1 km eye altitude. The image below is of one of the cliff faces. o Below create a sketch of the image above (which is a cross-section as it is a cliff face). Use arrows to indicate the direction of stress that created these features. 3 • Describe what you see. What happened to the rocks on the right side of the image? Click or tap here to enter text. • What is the name of the deformation feature? (name it completely; “fault” is not correct) Click or tap here to enter text. • What is the angle of dip on this feature (dip is measured from the horizontal)? Click or tap here to enter text. • How did the feature form? Give information about: • Type of stress • Characteristics of the rock that might influence how it deformed. Click or tap here to enter text. 4 ● Based on your answer above, at what type of plate boundary would you expect to find this feature? (Plausibility) Click or tap here to enter text. o In Google Earth Pro, zoom out from these outcrops or investigate this region on the Internet. What is this tectonic environment? (Plausibility) Click or tap here to enter text. 5

Worksheet 12 - Fall 2020
Completing your worksheet answering all questions in your own words.
Step 1. Folding
Ductile deformation of rocks results in folding.
o Open Google Earth Pro and navigate to Dent de Morcles, Switzerland.
Investigate the area - zooming in and out between ~12 km and 3 km eye altitude.
The image below is of the west-facing cliff face.

o Below create a sketch of the image above (it is a cross-section, because it is a cliff
face). Use arrows to indicate the direction of stress that created these features.
• How do you explain the lines on the cliff face? (Plausibility)

How do you think these rocks were deposited originally? Use a sketch in your
explanation if it is help...
