Oxygen (O2)
Nitrogen (N2)
Plus Water Vapor
Relative amount of Argon in the atmosphere - CORRECT ANSWER-1%
Relative amount of Carbon Dioxide in the atmosphere - CORRECT ANSWER-0.0401%
Relative amount of Oxygen in the atmosphere - CORRECT ANSWER-21%
Relative amount of Nitrogen in the atmosphere - CORRECT ANSWER-78%
Relative amount of Water Vapor in the atmosphere - CORRECT ANSWER-0-4%
Patterns of Motion and Driving forces of Motion - CORRECT ANSWER-Coriolis Force
Coriolis Force - CORRECT ANSWER-Objects in the Northern Hemisphere deflect to the
right and in the Southern Hemisphere ti the left
How does atmosphere circulation control climate? - CORRECT ANSWER-High
pressure = Descending air = DRY
Low pressure = Rising air = RAIN
BRAINSCAPE1

High Pressure - CORRECT ANSWER-Descending Air = DRY
Low Pressure - CORRECT ANSWER-Rising Air = RAIN
Humidity = water present/water max - CORRECT ANSWER-Cold: 1%/1% = 100%
humidity could/rain
Cool: 1%/2% = 50% humidity
Warm: 1%/3% = 33% humidity evaporation
Main Wind Belts - CORRECT ANSWER-Polar Easterlies
Westerlies
Easterlies
Easterlies - CORRECT ANSWER-weak-moderate, blow from east to west
Westerlies - CORRECT ANSWER-STRONGEST, blow from west to east
Polar Easterlies - CORRECT ANSWER-weak, seasonal, blow from east to west
How is Heat transported? - CORRECT ANSWER-with water!!!
How does water transport heat? - CORRECT ANSWER-•Condensation
*Vapor Liquid
*Energy out
•Evaporation
*Liquid Vapor
*Energy in
Weather prediction using atmospheric pressure - CORRECT ANSWER-High pressure =
DESCENDING AIR = DRY
Low pressure = RISING AIR = RAIN
Surface Currents - CORRECT ANSWER-moves cold water from poles to equator,
where the water is warmed before it goes back to the poles
Five Surface Currents - CORRECT ANSWER-Indian Ocean Gyre
North Pacific Gyre
South Pacific Gyre
North Atlantic Gyre
South Atlantic Gyre
What drives surface currents? - CORRECT ANSWER-Warm and cold currents, winds
push warm water west and cold water east
How do surface currents transport heat? - CORRECT ANSWER--sun warms near
equator
