  1. Atmosphere-Weather Earth Science Ch. 11

  2. Temperature vs. Heat • Temperature-measures how rapidly molecules are moving • Heat-transfer of energy • Flow is from hotter to colder

  3. Temperature scales-fig.11-7

  4. Converting degrees • F = (C x 1.8) + 32 • C = 5/9 (F-32) • 75-32=44x5/9= • 24 C

  5. Dew Point • Temp at which air must be cooled to reach saturation. • No dew or rain or snow til this temp occurs

  6. Wind • HowStuffWorks Videos "Basics of Geology: Wind“ • http://science.howstuffworks.com/search.php?terms=wind+energy&gallery=1&media=video

  7. Humidity-water vapor in air • Relative humidity= actual amt in air potential amt of moisture it can hold • (More on this in geode disk)

  8. Clouds Part 2

  9. How do clouds form? • Warm, moist air rises, then it expands and cools. • When it reaches its dew point, the water vapor condenses on condensation nuclei. • Ex. dust, smoke particles, sea salt • Millions collect, and clouds form

  10. 4 ways air rises. . .

  11. Weather _amp

  12. Orographic Lifting

  13. Convergence of air

  14. Frontal wedging

  15. In summary, 4 ways air rises

  16. Types of Clouds (table 11-3) • Classified by altitude and shape • Cirro-high cirrus-hair • Alto-middle cumulus-puffy • Strato-low stratus-layer • nimbus-rainy

  17. General Info • Cirrus clouds made of ice crystals • Fog is lowest form of clouds • Coalescence-cloud droplets colliding • They get big enough, and rain droplets form

  18. Precipitation • Rain, snow, sleet, hail • rime-ice that forms when water droplets freeze

  19. Assessment • 1. Describe the 4 ways air can rise. • 2. Describe how the water cycle works. • 3. Know how to identify cloud types. • 4. What are dew point and humidity?
