ÒtripletsÓ with one photograph in the middle and additional photographs on both the right and left sides. The stereoscope should be positioned to view Volcanism Questions 1. Figure 3.3 shows a volcano on the island of New Britain, north of Australia. First study the photos Òmonoscopically,Ó without the stereoscope. In the photos, water appears black. The top of the highstanding volcano shows a circular depression termed a summit crater. a. Sketch how the volcano might look from the ground. Sketch area 36 the middle and right photos as one image pair, and the middle and left photos as another image pair. Now position the stereoscope over the left dividing line and view the volcano in stereo. Reposition the stereoscope over the right seam and view this portion of the volcano in stereo. b. Observe and describe the shape of the summit crater. c. Do you think the summit crater formed by a single eruption or from multiple eruptions? Explain. d. List at least two pieces of evidence that the volcano has been eroded. e. Do you think the volcano is made of hard rock that is difficult to erode or soft ash that is easy to erode? Explain. *f. Why is the volcano more heavily forested on one side than the other?

Gradation 2. Figure 3.4 shows a portion of White Sands, New Mexico, an area affected by aeolian (wind) processes. The crescent-shaped features are dunes composed of sand. Most sand dunes have a gentle slope on their windward side and a steeper slope to the leeward side. High velocity winds blow sand up the windward side to the brink of the dune; sand then slides down the leeward slip face of the dune. a. Examine the photographs stereoscopically and identify the slip faces on the dunes. From which direction is the wind blowing? b. Consider one of the dunes near the center of the photo. Where will its sand go in time? c. How does the morphology of the sand dunes change across the photo? Use sketches of at least two dunes to illustrate your answer.
