Astronomy of the Solar System-DL-B Martha Fernandez-Lopez Quiz # 4 Question 1 4 Points Most of the Moon's surface is densely covered with craters, but we find relatively few craters within the lunar maria. What can we conclude? A Erosion affects the maria more than it affects other regions of the Moon. B The maria formed after the heavy bombardment ended. C The regions of the maria were hit by fewer impacts than the densely cratered regions. D The maria formed within the past 1 billion years. Question 2 4 Points Which of the following worlds has the most substantial atmosphere? A Mercury B Mars C Earth D Venus E the Moon Question 3 4 Points
The current atmospheric concentration of carbon dioxide on Earth is at its highest in over a million years. A True B False Question 4 4 Points We are confident that rising CO 2 levels are caused by the burning of fossil fuels because atmospheric CO 2 now has the same carbon isotope ratio as fossil fuels. A True B False Question 5 4 Points Earth is habitable because of the greenhouse effect. A True B False Question 6 4 Points According to our theory of solar system formation, what are asteroids and comets? A chunks of rock or ice that condensed after the planets and moons finished forming B leftover planetesimals that never accreted into planets C the shattered remains of collisions between planets
D chunks of rock or ice that were expelled from planets by volcanoes Question 7 4 Points Jupiter and the other gas giants formed close to the sun and migrated outward. A True B False Question 8 4 Points According to our theory of solar system formation, which law best explains why the central regions of the solar nebula got hotter as the nebula shrank in size? A Newton's third law B the law of conservation of angular momentum C the two laws of thermal radiation D the law of conservation of energy Question 9 4 Points At greater distances from the sun, planetary surface temperatures increase. A True B False Question 10 4 Points Which of the following types of material can condense into what we call ice at low temperatures?
A rock B metal C hydrogen compounds D hydrogen and helium Question 11 4 Points Earth is the only terrestrial planet to have experienced tectonic stresses and volcanic activity. A True B False Question 12 4 Points Which of the following best describes convection? A It is the process in which a liquid separates according to density, such as oil and water separating in a jar. B It is the process by which rocks sink in water. C It is the process in which bubbles of gas move upward through a liquid. D It is the process in which warm material gets even warmer and cool material gets even cooler.
