Catastrophic Events Ch 1-7 Take Home Final; answer the following questions, in your own words, using your brain, Science Notebook, or Catastrophic Events textbook, heck you can google it if you want. Explanations must be LEGIBLY hand written or, preferably, typed. 1. Name: Period: Date: What is a vortex, and what causes it to form (look at notes)? 2. Describe what happens to air above a heated surface. 3. Describe what happens to air above a cold surface. Storms Vocabulary ~ You should be using these terms in your explanations to the questions…. 4. Explain what happens when hot air meets cold air? Vortex Globe Map 5. Describe the formation of hurricanes? Thunderstorm Hurricane Tornado 6. Compare and Contrast tornadoes and hurricanes Stable air mass Unstable air mass Convection currents Conduction Radiation Weather front Humidity/water vapor a. How are they alike? (2 things) b. How are they different? (5 things) 7. Describe the role the sun plays in the weather on earth? 8. Describe what a convection current is and how it forms? 9. Look at your graph from Lesson 3. Write a 4-sentence conclusion paragraph answering the following question: What type of surface heats faster? 12. Study the illustration of Tornado Alley on page 65. Answer the following: a. What states make up Tornado Alley? b. What causes tornadoes to form in Tornado Alley? Expand Contract Less dense More dense Compress Pressure (air) Temperature Clouds Condensation Evaporation Precipitation Transpiration Coriolis effect Trade winds Easterly Westerly Jet stream Look at the illustration of a sea breeze and a land breeze on page 59. 10. What is a sea breeze, when does it form, explain why it forms? 11. What is a land breeze, when does it form, explain why it forms? 13. Look at the illustration of the water cycle on page 72. Illustrate and describe the water cycle (attach a piece of paper) 14. Look at the weather maps on page 70. a. Where is the pressure high? What is the weather like here? b. Where is the pressure low? What is the weather like here? 15. How do clouds form? Be specific in describing the process – what is required? 16. Thin about the investigation in Lesson 7 in which you modeled ocean currents with potassium permanganate. a. How do some deep currents form (think fish tank up front)? b. How do winds affect ocean currents (think straw)? c. How do ocean currents affect air temperatures around the world? d. Describe the sun’s role in forming ocean currents. 17. Looking at your or a current map, why is Iceland green and Greenland white? 18. Why is the Pacific Northwest generally cool and moist? Explain why… 19. If you wanted to go swimming in South America, which side of the continent would be warmer? Explain why… 20. Describe the composition and properties of the troposphere and stratosphere.
