Atmosphere-Weather Earth Science Ch. 11

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

Temperature scales-fig.11-7

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

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

Wind HowStuffWorks Videos "Basics of Geology: Wind“ HowStuffWorks Videos "Basics of Geology: Wind“ fworks.com/search.ph p?terms=wind+energ y&gallery=1&media=v ideo fworks.com/search.ph p?terms=wind+energ y&gallery=1&media=v ideo

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

Clouds Part 2

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

4 ways air rises...

Weather _amp

Orographic Lifting

Convergence of air

Frontal wedging

In summary, 4 ways air rises

Types of Clouds (table 11-3) Classified by altitude and shape Cirro-highcirrus-hair Alto-middlecumulus-puffy Strato-lowstratus-layer nimbus-rainy

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

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

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?
