Integrated Science Energy and the Geosphere: Test Review Name___________________________________ Period__________________________________ In addition to this review, you should also study your notes, labs, worksheets and anything else you have used in class. Earthquakes: 1. What kind of tectonic plate boundary caused the earthquake in Haiti? 2. What instrument is used to measure waves within in the earth? 3. What is an epicenter? What is a focus? 4. What information from a seismograph is used to determine the epicenter of an earthquake? 5. How many stations are needed to locate the epicenter of an earthquake, and what is this locating process called? Plate Tectonics and Density: 6. Discuss the theory of plate tectonics. 7. Who is given credit for first proposing the theory of continental drift? What evidence is there to support this theory? 8. Describe the crust, mantle, and core of the Earth. 9. What is meant by lithosphere? What is meant by asthenosphere? 10. What type of heat transfer is responsible for the movement of the Earth’s plates, and why is the Earth’s interior hot? 11. Describe how the Earth’s plates move as a result of energy being transferred from the source. 12. What are the two types of tectonic plates? Which one is more dense? 13. Describe each of the following types of plates boundaries: Convergent: Divergent: Transform: 14. What types of structures/events occur at each of the following types of plate boundaries? Continental/continental convergent: Oceanic/oceanic divergent: Continental/oceanic convergent: 15. When a substance heats up, what tends to happen to its volume? What happens to its density? 16. When a substance’s density is greater than the density of the material around it, what does it do? 17. Calculate the density of a 90cm3, 800g sample of rock. (Show your work.) 18. Calculate the mass of a 540 cm3 rock with a density of 5.3 g/cm3. (Show your work.) Volcanoes: 19. Describe the ‘Ring of Fire’. (Where is it? What plates and plate boundaries are responsible for its formation?) 20. Describe the three different types of volcanoes. 21. What kinds of gases are released from volcanoes? Why do scientists study these gases? 22. Define ‘threshold value’ and explain how this relates to the study of volcanic gases. Radioactive Decay 23. Briefly describe the structure of the atom. (What are the 3 types of subatomic particles, and where are they found?) 24. What are isotopes? How does this idea help explain why the atomic mass listed for each element on the periodic table is not a whole number? 25. Fill in the following chart: Name Potassium-40 Carbon-____ _____________-15 ___________-____ 7 1 # of Protons 8 # of Neutrons 1 26. What particles are in the nucleus? What are their charges? How does this affect the stability of the nucleus? 27. What are the two forces that must balance in a nucleus, in order for it to be stable? Is each one attractive or repulsive? What particles are affected by each one? 28. How many protons are found in the nucleus of the largest completely stable type of nucleus? 29. What is being released in each of the 3 types of nuclear decay? How energetic/penetrating is each one? 30. Fill in the missing product from this decay reaction: 184 74W ______ 180 72 Hf 31. When Polonium-214 decays by alpha decay, what product is formed? 32. What is the meaning of half-life? 33. If a radioactive sample initially has a mass of 200 grams, how much will be left after two half-lives have occurred? 34. How is radioactive decay related to ‘Energy and the Geosphere’?
