Start on the home screen of the interactive figure, with "Elevation is off." Then turn elevation on, and compare what you see. You may wish to switch back and forth between elevation on and off a few times. Then select the statements below that are true. Note: Features such as impact craters that are actually round in shape are distorted into oval shapes at mid- to high-latitudes by map projection effects.
A. The icy polar caps have the highest elevations of any features on Mars. B. There is a long, deep canyon that stretches along a region close to Mars's equator. C. Most of the northern hemisphere has much lower elevation than the southern hemisphere. D. The northern hemisphere is more heavily cratered than the southern hemisphere. E. There is a large, roundish region of low-elevation in the southern hemisphere. F. Several large volcanoes are found near or somewhat north of Mars's equator.
