NAME________________________ CP Geoscience PERIOD_______ DATE_________ Unit 2: EARTH AS A PLANET TEST #1 REVIEW The first test of Unit 2 will include the formation of the solar system and types of planets, the motions of the earth, the layers of the Earth and the basic structure of the atmosphere. Terms to Know: Stellar nebula hypothesis Accretion Terrestrial Jovian Differentiation Core Mantle Crust Lithosphere Moho Trophosphere Stratosphere Mesosphere Thermosphere Exopsphere Ridge push Slab pull Eccentricity Obliquity Precession Summer solstice Winter solstice Spring equinox Autumnal equinox Aphelion Perihelion Concepts to Know: 1. Describe the stages in the formation of the solar system (formation of the sun and planets)? 2. What caused the nebula to collapse? 3. What evidence is there to support the solar system came from the explosion of a super nova 4. Why are the inner planets rocky and the outer planets gaseous? 5. Which planets are more like the sun? Why? NAME________________________ CP Geoscience PERIOD_______ DATE_________ 6. What are the characteristics of the terrestrial planets? 7. What are the characteristics of the Jovian planets? 8. Why is Earth’s interior differentiated? 9. List and describe (composition and function) each layer of the Earth’s interior. 10. Which parts of the layers are contained in the lithosphere? 11. What is the importance of Earth’s metal core? 12. What are the two different types of crust? Which is denser? Why? NAME________________________ CP Geoscience PERIOD_______ DATE_________ 13. How was our current atmosphere formed? 14. What are the main elements that comprise our atmosphere? 15. Name and describe the characteristics of each layer of our atmosphere 16. Describe the changes in temperature as you move up through the atmosphere 17. Describe the changes in pressure as you move up through the atmosphere 18. Explain how the earth moves: around its axis and around the sun. NAME________________________ CP Geoscience PERIOD_______ DATE_________ 19. What is the main contributor of our seasonal changes? Why is this so? Add a diagram to clarify. 20. The Milankovitch Cycle is used to predict Ice Ages. When all three of these characteristics are at a maximum, we are believed to be in an Ice Age. List and define each of the three characteristics.
