Attempt due: Oct 15 at 11:59pm Modules Specific Learning Goals: 1 Hour, 54 Minutes, 0 Seconds People 1. Describe the differences between terrestrial and jovian planets (and asteroids/comets) Pages 2. Explain what influences the temperature of a planet'’s surface 3. Explain why there is geological activity on some bodies and not on others | Quizzes Learner Support R 4 Resources [ Question1 1pts Learner Support Resources Surprising discovery? Saturn's core is pockmarked with impact craters and dotted with volcanoes erupting basaltic lava. Zoom ) Implausible. Saturn's high rotation would prevent an impactor from reaching its core. O Plausible. Saturn's moons also show impact craters and volcanoes. ® Implausible. No impactors would survive the immense pressures at the depth of Saturn's core ) Implausible. Any large impactor approaching Saturn would be broken up by tidal forces. O Plausible. Saturn's atmosphere originated from the volatiles in impactors that were released via volcanic activity. [ Question 2 1pts Surprising discovery? A mission to the outer solar system finds a new dwarf planet that has lakes of liquid water on its surface. ) Implausible. Plutoids are mostly made of rock and metals, not water. ® Implausible. Water would be frozen at the equilibrium temperature of a body in the outer solar system, and we know of no extra heat sources. O Plausible. Other icy bodies at great distances from the Sun may also have liquid water. ) Plausible. Studies of Pluto's surface show a long, narrow feature that has been suggested to be a lake. Question 3 1pts Why do Jupiter, Saturn, Uranus, and Neptune all have rings? ® All have small moons and small orbiting particles that constantly collide and make rings ) They all captured particles O All four planets had a large moon that disintegrated ) Rings were left over from solar system formation [ Question 4 1pts Surprising discovery? A jovian planet in another star system is found to have a moon as big as Mars. O Implausible. Any moon that was as large as Mars would be called a planet it its own right ) Plausible. Astronomers have already found large planets and moons around other star systems. O Implausible. Any moon that was as large as Mars would be torn apart by tidal forces. O Plausible. Jupiter itself has several moons as large as Mars. @® Plausible. There is no reason why jovian planets cannot have such large moons. Question 5 1pts The terrestrial planets are different from the giant planets because when they formed: (Choose the best answer.) O the inner solar system was moving faster, so centrifugal force was more important. O the inner solar system was richer in heavy elements. O the outer solar system took up a bigger volume, so there was more material to form planets. @ the inner solar system was hotter than the outer solar system. No new data to save.
