ce-shaping processes that occur on a planet throughout its history will determine how its surface appears. The terrestrial planets were formed in basically the same environment, so we can assume that the average frequency of impacts for all of the terrestrial planets has been about the same. In a hypothetical scenario where impacts are the only process that ever shape planetary surfaces, how would the surfaces of the terrestrial planets compare? (Tip: Note that “craters per area” refers to the number of craters in the same-sized region on each planet—for example, craters per square meter.) Choose one: A. The smaller planets would have more craters per area than the larger planets. B. The planets closer to the Sun would have significantly more craters per area than the more distant planets. C. The larger planets would have more craters per area than the smaller planets. D. All of the planets would have roughly the same num
