Weathering and Erosion: One of Alfred Wegener’s lines of evidence for Continental Drift Hypothesis and the existence of the super-continent of Pangea involved the “Continuity of Mountain Ranges.” Specifically, modern active mountain ranges are continuous, whereas older mountain ranges are discontinuous suggesting that they had been broken into shorter segments due to the break-up of Pangea. Use the images below to infer how Wegener determined ancient from active mountains by answering the following questions about the ranges. (Three are correct).

Seismology: The image below shows the seismic body wave velocities (x-axis) of S and P waves passing through Earth from the surface to the center of the planet (y-axis). Determine the approximate depth (km) of the base (bottom) of each of Earth’s Rheologic layers (e.g., 100, 900, 1100, 2500): By 100’s, in other words NO numbers like 3157. Do NOT include units (numbers only) Base of the lithosphere [1] Base of the asthenosphere [2] Base of the mesosphere [3] Base of the outer core [4] Base of the inner core [5]
