GEOLOGY 12 CHAPTER 22 WORKSHEET COMPARATIVE PLANETOLOGY Name References: Video: Overview of the Solar System (Standard Deviants 30 minutes) Text: pages 165-167 and 475-501 CDROM (Library): Exploring the Planets-Advanced Level INTRODUCTION (VIDEO) Record 2 or 3 distinguishing characteristics (i.e. no atmosphere, cratered, volcanoes, direction of rotation, etc.) for each planet and their major moons. (Note: 1 A.U. or astronomical unit = the distance from the Earth to the Sun) Mercury Venus Mars Jupiter Saturn Uranus Neptune Pluto
THE NEBULAR THEORY TEXT (and CDROM Exploring the Planets: Introduction ) The basic premise of the Nebular Model or Theory is that planets vary in their composition as a consequence of their distance from the sun, and, their development was a result of this composition and their size. Use the information on page 166, 476-477 and 486 to explain why the planets are classified as terrestrial (inner) and Jovian (outer).
PLANETARY PROCESSES (see CDROM Exploring the Planets ) From the main menu choose Planetary Processes. Read the captions for each of the following processes. (An excellent review opportunity!) Click on the Link to Planet button when it flashes to explore photos of these features and make note of the planets and moons that exhibit evidence of these processes. A. LANDSLIDES B. VOLCANISM Shield Volcanoes Composite Volcanoes Cinder Cones Caldera C. FLOWING WATER Canyons Flood Channels D. WIND Desert Pavement Dunes E. IMPACT CRATERING (Craters) F. TECTONICS Strike-Slip Faults Folding Normal Faults / Fault Blocks / Graben + Horsts

Which of the following is best explained by the Nebular Hypothesis of the solar system s formation? A. Some planets do not have an atmosphere. B. Most planets have cooler surface temperatures than Earth. C. Some outer planets have higher internal temperatures than inner planets. D. Inner planets have rocky compositions, outer planets have gaseous compositions. 55. The best reason for a lack of cratering on Venus, is that Venus has a(n) A. acidic atmosphere. B. weak magnetic field. C. variety of active geologic processes. D. weaker gravitational pull than Earth.
53. The most heavily cratered solid bodies in the solar system also have the A. deepest oceans. B. thickest atmospheres. C. least tectonic activity. D. highest internal temperatures. 54. Which of the following solar system bodies shows evidence of flowing water at some time in its history? A. Mars B. Moon C. Venus D. Jupiter 55. The Nebular Model of the origin of the solar system suggests that the outer planets consist of lighter, easily evaporated materials because these materials would condense where A. pressures were lower. B. pressures were higher. C. temperatures were lower. D. temperatures were higher.

11. Describe three characteristics of the planets of our solar system, other than distance from the sun, that justify their classification into inner and outer groups. As there is some question at this time whether Pluto is a planet, omit Pluto from your answer. (3 marks) CHARACTERISTIC INNER PLANETS OUTER PLANETS Example: Distance from the sun. Four inner planets are closer to the sun. Outer planets are farther away from the sun than inner planets are. 1. 2. 3.
REFERENCE DATA ÊBOOKLET Refer to page x of the Data Booklet. Use the Basic Data on the Solar System chart to answer question 14. 14. a) Density can be used to divide the planets into two groups: the inner and outer planets. What difference in composition would account for the difference in density of the two groups? (1 mark) b) Describe how the Nebular Theory of the origin of the solar system explains the difference in density between the inner and outer planets. (1 mark)
