Passage III
When an asteroid hits the surface of a planet or moon, an impact crater is formed. An asteroid that hits Earth under a specific set of conditions (including speed and angle), referred to here as Set C, forms a crater with a diameter about 20 times the asteroid's diameter. Figure 1 shows the energy released by the impact, for a range of asteroid diameters.
Figure 2 shows the average amount of time that elapses between consecutive impacts on Earth by asteroids with the same diameter, for a range of asteroid diameters. Figure 3 shows the percent of the surface of the Moon, Mercury, and Mars that is covered by impact craters, for various ranges of crater diameter.
15. According to Figure 3, for any given range of crater diameters, the percent of the surface of Mars that is covered by impact craters with those diameters is:
Your Answer is
Correct Answer is A
Explanation
Looking at figure 3, the pillar representing Mars is always the shortest, indicating that under the same impact crater diameter, the percentage of surface covered on Mars is the smallest
