  1. OBJECTIVE: Review for Final • FINISH YOUR STUDY GUIDE!!!!

  2. Final Exam Study Guide

  3. 1. How do thunderstorms form? • Warm moist air rises forcefully • Water vapor condenses providing energy for the storm • Updrafts and downdrafts maintain storms energy • Storm dissipates when it runs out of energy

  4. 2. Where do they form? • Along cold fronts

  5. 3. How is lightning created? • Electrical discharge between two oppositely charged surfaces.

  6. 4. Where can lightning travel? • From one part of the cloud to another part • From one cloud to another cloud • From cloud to ground

  7. 5. What is thunder? • Rapidly expanding and contracting air from the lightning bolt creates sound waves

  8. 6. What kinds of clouds produce tornadoes? • Cumulonimbus clouds

  9. 7. What is a supercell? • Powerful thunderstorm that can produce tornadoes

  10. 8. How do tornadoes form? • Warm and cold air meet and rotates horizontally • Updrafts push column of air vertical • Rotating air descends it picks up dirt and debris

  11. 9. What is a hurricane? How do they form? • Massive tropical cyclone that forms over warm waters, with extremely strong winds and rain • Water vapor evaporating and then condensing within the storm gives it energy • As clusters of thunderstorms strengthen, they begin to rotate

  12. 10. Where do each of these tropical cyclone form? • Cyclone • Hurricane • Typhoon • Indian Ocean • Atlantic Ocean • Pacific Ocean

  13. 11. What is the rainband of hurricane? • Region of heavy thunderstorms beyond the eyewall that spiral outward from the center of a hurricane

  14. 12. What is the Coriolis Effect? • Spiraling of winds due to the Earth’s rotation

  15. 13. What is the eye of the hurricane? And what is the pressure there (high or low)? • Circular region located at the center of a hurricane • Warm air is rising, creating a low pressure zone • Surrounded by the eyewall which is the most destructive part of a hurricane.

  16. 14. What is global warming? • A gradual increase in average global temperature • Due to: • Burning of fossil fuels • Extra heat in the atmosphere • Greenhouse Effect trapping more heat than normal • Normally a natural process, but humans are speeding it up, thus making it worse.

  17. 15. What are the two gases that make up most of our atmosphere? • Nitrogen • Oxygen

  18. 16. What is wind? • Movement of air from high to low pressure

  19. 17. What are the three phases of matter? Describe each phase. • Solid • particles are barely moving • Substances hold their own shape and do not flow • Liquid • particles are moving slowly • Substances take on the shape of their container and flow • Gas • Particles are moving quickly • Substance fills the shape of it’s container and flows

  20. 18. What is the Fujita Scale? • Measures the intensity of a tornado • F0 – F5

  21. 19. Where is Tornado Alley located? • American Midwest • Great Plains

  22. 20. What can destroy/diminish a hurricane? • Wind shear • Cold water • Land • Saharan Air Layer

  23. 21. What is a front? • The boundary between air masses

  24. 22. Describe the weather at each of these fronts: • Cold front • Warm front • Stationary front • Occluded front • Severe thunderstorms • Drizzly weather • Many cloudy and rainy days • Cool temp. & a lot of rain

  25. 23. Describe each layer of the atmosphere: • Troposphere • Stratosphere • Mesosphere • Thermosphere • All weather happens here • Ozone layer • Meteor’s burn up • Hottest but you would feel cold/ satellites fly here

  26. 24. Describe each type of air mass: • Maritime polar • Maritime tropical • Continental polar • Continental tropical • Moist, cold • Moist, warm • Dry, cold • Dry, warm

  27. 25. What is the water cycle? What powers it? • Continuous movement of water within Earth’s atmosphere, land, and oceans/lakes • Sun

  28. 26. Create a flow map of the water cycle. Cloud / Condensation Precipitation Evaporation Runoff Ocean/Lake Infiltration / Percolation

  29. 27. What happens to water content as warm rises? As it cools? • Warm air rises and becomes cooler, it loses the ability to hold water • Cool air sinks and becomes warmer, it gains the ability to hold water

  30. 28. What is the Greenhouse Effect? • Greenhouse gases trap heat and keep the Earth warm

  31. 29. What causes the seasons? • Tilt of the Earth’s axis

  32. 30. Why type of star is the hottest (blue or red)? • blue

  33. 31. What could happen when a star dies? • White Dwarf • Supernova • Neutron star • Pulsar • Black hole

  34. 32. How are craters formed on the Moon? • Asteroid/meteoroid impacts

  35. 33. List the contributions of each of these astronomers: • Ptolemy • Copernicus • Tycho Brahe • Johannes Kepler • Galileo Galilie • Isaac Newton • Edwin Hubble • Geocentric universe • Heliocentric universe • Made large, detailed instruments • Used Brahe’s work to prove heliocentric universe • Used telescope • Law of gravity • Discovered many other galaxies / universe bigger than imagined

  36. 34. How many stars are in our solar system? • 1 – OUR SUN!!!

  37. 35. What type of star is our Sun? • Main-sequence Star

  38. 36. What are sunspots? • Cooler, darker areas of the Sun

  39. 37. What is astronomy? • The study of the universe

  40. 38. What is the difference between a refracting and reflecting telescope? Which one is more accurate? • Refracting telescope • Lenses bend light to eyepiece • Negatives: • Cannot make them too big • Do not focus perfectly • Reflecting telescope • mirrors bounce light to eyepiece • More accurate

  41. 39. Describe each part of the electromagnetic spectrum: • Radio waves • Microwaves • Infrared • Visible light • Ultraviolet light • X-rays • Gamma rays • Radios use them • Microwaves use them • Heat energy • Energy we see / colors • Gives you a suntan/sunburn • High energy that cannot go through solids • Incredibly high energy

  42. 40. List facts for each planet: • Mercury • Venus • Earth • Mars • Jupiter • Saturn • Uranus • Neptune • Smallest planet • Year is longer than a day • Only one with life • Largest volcano • Largest planet • Has visible rings around it • Diamonds possibly in the core • Sonic speed winds

  43. 41. What is a solar eclipse? Lunar eclipse? • Solar eclipse - When the Moon comes in between the Sun and Earth and casts a shadow on the Earth • Lunar eclipse - When the Moon gets covered by the Earth’s shadow
