Biology 150 Exam II
Chapter 52 - Global Climate Patterns
| Question | Answer |
|---|---|
| Latitudinal Variation in Sunlight Intensity | earth's curved shape causes latitudinal variation in the intensity of sunlight; sunlight strikes the tropics most directly 23.5° north and 23.5° south latitude. |
| Seasonal Variation in Sunlight Intensity | earth's tilt causes seasonal variation in the intensity of solar radiation. the tropics experience the greatest annual input of solar radiation, and the least seasonal variation. |
| Global Air Circulation and Precipitation Patterns | intense solar radiation near the equator inititiates a global pattern of air circulation and precipitation. ascending moist air releases moisture, descending dry air absorbs moisture. |
| Global Wind Patterns | air flowing close to earth's surfaces creates predictable global wind patterns. as earth rotates, land near the equator moves faster than at the poles. |
