What is the principal geologic process that has shaped this part of Rhea?
Give evidence from the data for your response. Notice the morphologies (shapes) of the craters that you see in Figure 13.3. The 60-km crater A shows a sharp and distinct morphology, with steep and well-defined slopes. On the other hand, the 65 km crater B is more difficult to identify, as it is rounded and indistinct. Keep in mind that the cratered surface of Rhea seen is probably about 4 billion years old. • Lay a piece of acetate over Figure 13.3, taping it at the top. Trace the rectangular outline of the photo, and also trace and label the scale bar. With a solid line, trace the outline of crater A, and label the crater “sharp.” Next locate and trace the outline of crater B, but this time use a dashed line. Label this crater “subdued.” Locate one additional sharp crater, outlining it with a solid line. Find an additional subdued crater, and outline it with a dashed line. The terms “sharp” and “subdued” are descriptive terms, used to describe the morphologies of craters. Sharp-appear
