Venus Jupiter Neptune Mars 1.12 points Question 9 Whit is special about Jupiter's Moon Europa? It is the only large moon in orbit around Jupiter It is the most volcanically active world in the solar system It is the largest moon in the solar system It has a water ice crust with an ocean of liquid water below. 1.12 points Question 10 If you were looking down at the North pole of the Sun, how would the orbits of the planets appear? All planets orbit the Sun clockwise All planets orbit around the Sun counterclockwise All the orbits are in different directions and orientations, purely at random The inner planets orbit clockwise, the outer planets orbit counterclockwise 1.12 points Question 11 What is the Sun mostly made of?

Only Nitrogen Nitrogen and Oxygen Iron and nickel metals Hydrogen and Helium gas 1.12 points Question 13 What were the main gases in the giant cloud that formed our Sun and planets? Carbon Dioxide Nitrogen and Oxygen Only Nitrogen Hydrogen and Helium 1.12 points Question 14 Which of the following are rocky objects left over from the formation of our solar system? Comets Kuiper Belt Saturn Asteroids 1.12 points Question 15 Which of the following in an example of an Icy leftover from the formation of our Solar system? Our Moon Asteroids Comets Nebula 1.12 points Question 16 The "frost line" is useful to explain which of the following? Location of the Jovian planets The size of Earth's North pole The altitude in the Earth's atmosphere above which water will freeze The size of a planet's moons 1.12 points Question 17 Which of the properties of the solar system can be explained by Conservation of Angular Momentum? All planets orbit the Sun in the same direction and plane Uranus and Neptune are bluish in appearance Jovian planets are found far from the Sun Earth is rocky and Jupiter is gaseous 1.12 points Question 18 Conservation of Energy can explain which of the following properties of our solar system? Planets nearer the Sun formed at higher temperatures where only rocks and metals could solidify. Thus, we find rocky worlds close to the Sun. Large moons orbit around Jovian planets in the same direction and plane Only Jovian planets have multiple large moons Mercury and our Moon are both heavily cratered
