OBJECTIVE: Review for Final • FINISH YOUR STUDY GUIDE!!!!
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
2. Where do they form? • Along cold fronts
3. How is lightning created? • Electrical discharge between two oppositely charged surfaces.
4. Where can lightning travel? • From one part of the cloud to another part • From one cloud to another cloud • From cloud to ground
5. What is thunder? • Rapidly expanding and contracting air from the lightning bolt creates sound waves
6. What kinds of clouds produce tornadoes? • Cumulonimbus clouds
7. What is a supercell? • Powerful thunderstorm that can produce tornadoes
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
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
10. Where do each of these tropical cyclone form? • Cyclone • Hurricane • Typhoon • Indian Ocean • Atlantic Ocean • Pacific Ocean
11. What is the rainband of hurricane? • Region of heavy thunderstorms beyond the eyewall that spiral outward from the center of a hurricane
12. What is the Coriolis Effect? • Spiraling of winds due to the Earth’s rotation
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.
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.
15. What are the two gases that make up most of our atmosphere? • Nitrogen • Oxygen
16. What is wind? • Movement of air from high to low pressure
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
18. What is the Fujita Scale? • Measures the intensity of a tornado • F0 – F5
19. Where is Tornado Alley located? • American Midwest • Great Plains
20. What can destroy/diminish a hurricane? • Wind shear • Cold water • Land • Saharan Air Layer
21. What is a front? • The boundary between air masses
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
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
24. Describe each type of air mass: • Maritime polar • Maritime tropical • Continental polar • Continental tropical • Moist, cold • Moist, warm • Dry, cold • Dry, warm
25. What is the water cycle? What powers it? • Continuous movement of water within Earth’s atmosphere, land, and oceans/lakes • Sun
26. Create a flow map of the water cycle. Cloud / Condensation Precipitation Evaporation Runoff Ocean/Lake Infiltration / Percolation
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
28. What is the Greenhouse Effect? • Greenhouse gases trap heat and keep the Earth warm
29. What causes the seasons? • Tilt of the Earth’s axis
31. What could happen when a star dies? • White Dwarf • Supernova • Neutron star • Pulsar • Black hole
32. How are craters formed on the Moon? • Asteroid/meteoroid impacts
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
34. How many stars are in our solar system? • 1 – OUR SUN!!!
35. What type of star is our Sun? • Main-sequence Star
36. What are sunspots? • Cooler, darker areas of the Sun
37. What is astronomy? • The study of the universe
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
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
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
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
