With which of the following statements about the conditions on Europa or the evolution of Europa's surface would both Scientist 1 and Scientist 2 most likely agree? The surface of Europa: Individual Question - Correct Answer is being shaped by the movement of ice. Which of the following statements about meteorite craters on Europa would be most consistent with both scientists' views? - Correct Answer Meteorite craters, once formed, are then smoothed or removed by Europa's surface processes. Scientist 2 explains that ice sublimes to water vapor and enters Europa's atmosphere. If ultraviolet light then broke those water vapor molecules apart, which of the following gases would one most likely expect to find in Europa's atmosphere as a result of this process? - Correct Answer Oxygen Based on the information in Scientist 1's view, which of the following materials must be present on Europa if a magnetic field is to be generated on Europa? - Correct Answer Dissolved salts Assume Scientist 2's view about the similarities between Europa's surface features and flowing glaciers on Earth is correct. Based on this assumption and the information provided, Earth's glaciers would be least likely to exhibit which of the following features? - Correct Answer Meteorite craters Which of the following best describes the difference between the procedures used in Experiments 1 and 2 ?
