Explain the processes occurring in the figure above that are generating magma. At what kind of tectonic boundary are such processes common?
What will be an ideal response?
Answer: As rifting occurs at the divergent boundary, pressure is decreased at that point on the mantle. Decompression melting generates magma.

There are five small glaciers shown on this map (glaciers are shown as white patches with blue contour lines). Why can glaciers survive today in these locations but not in others?
The question is based on Map T-13, the “Mono Craters, California” quadrangle (scale 1:62,500; contour interval 80 feet), and Figures 48-5 and 48-7, a detailed map and stereogram, and Map T-23a, a satellite image, of the same region. The heavily glaciated eastern crest of the Sierra Nevada is seen along the western sides of the map and stereograms (37°52'37"N, 119°12'40"W). During the Pleistocene, glaciers in this region flowed down the valleys of the eastern slope of the Sierra toward the Mono Lake basin to the northeast. Large lateral moraines are found at the mouths of each canyon. What will be an ideal response?
