Which jovian planet should have the most extreme seasonal changes? Why? Uranus, because of its tilt Why is the radiation so intense in the region that traces Io's orbit around Jupiter (the Io torus)? The region is full of gases that become ionized after they are released from volcanoes on Io. Which of the following best explains why many jovian moons have been more geologically active than the Moon or Mercury? Jovian moons are made mostly of ice that can melt or deform at lower temperatures than can the rock and metal that make up the Moon and Mercury. All the following statements are true. Which one is most important in explaining the tremendous tidal heating that occurs on Io? Io orbits Jupiter on an elliptical orbit, due to orbital resonances with other satellites. Which of the following is not a piece of evidence supporting the idea that Europa may have a subsurface ocean? Astronomers have detected small lakes of liquid water on Europa's surface. Could liquid water be found on Titan? No, it's surface temperature is much too cold. Why do astronomers believe that Triton is a captured moon? Triton's orbit of Neptune is opposite Which statement about Saturn's rings is NOT true? The rings look much the same today as they did when Saturn formed. According to current understanding, what is required for a planet to have rings? The planet must have many small moons that orbit relatively close to the planet in its equatorial plane. When you see the bright flash of a meteor, what are you actually seeing? The glow from a pea-sized particle and the surrounding air as the particle burns up in our atmosphere What is the size of the largest asteroid, Ceres? It is about half the diameter of our moon If we could put all the asteroids together, their total mass would be _________. Much less the mass of any terrestrial planet Why didn't a planet form where the asteroid belt is now located? Jupiter's gravitational tugs Gaps in the asteroid belt (often called Kirkwood gaps) are caused by ______. Orbital resonances from jupiter In science fiction movies, spaceships are often shown dodging through large numbers of closely spaced, boulder-size objects. Which of the following real things in our solar system would look most like such science fiction dangers? Saturns rings Suppose you find a meteorite made almost entirely of metal. According to current science, which of the following statements must be true? Your meteorite is a fragment from the core of a large asteroid that shattered in a collision. Which of the following objects are probably not located in the same general region of the solar system in which they originally formed? Oort cloud comets
