Earth Science - New York Regents January 2007 Exam
Base your answers to questions 66 through 69 on the graph below, which shows two conditions responsible for the formation and composition of some planets in our solar system. The distances of Earth and Neptune from the Sun, in astronomical units (AU), are shown beneath the horizontal axis. (1 AU = 149.6 million kilometers). The plotted line on this graph shows the relationship between a planet’s distance from the Sun and the inferred temperature at its formation. The regions within the graph indicate the composition of planets formed within these zones.
