Document Summary

Osu geography 1900 extreme weather and climate midterm 1 study guide. Scientific method: hypothesis, prediction, experiment, analysis, conclusion. Weather: state of atmosphere at a particular moment. Climate: the statistics (average & variability) of weather. Expected difference between min. and max. temps tomorrow. Beginning of solar system: spinning dust-cloud electrostatic and gravity. Formation of earth accretion; small particles clump together, begin colliding, gain gravity attract more particles ( planetesimals ), becomes larger proto-planet. Very early atmosphere ~4. 6 billion years ago. Mostly h2 and he--gases present in dust cloud. Lost to space (heat, solar wind, and earth"s small mass) Early atmosphere ~4. 6 to 4. 2 billion years ago. Contraction heating volcanic activity outgassing and potentially impact degassing. Surface temperature between 85 - 100 c. Reduced volcanism- 4. 2 to 3. 8 billion years ago. Cooling and precipitation cause a decrease in: Increase in atmospheric o2 caused by advent of photosynthesis (~3. 5 billion years ago) Sunlight h2o + co2 {ch2o} + o2.
