Document Summary
Chapter 3 notes the global energy system first. Atmosphere likely consisted of helium, hydrogen, ammonia, and methane at. Signs of carbon dioxide began to come up. Atmosphere went from being oxygen-poor to oxygen-rich. Photosynthesis led to a rapid increase in oxygen. Almost all of the atmosphere"s mass is accounted for within 30 km of earth"s radiating some of the heat back to earth"s surface. Condensation nuclei: a tiny particle of solid matter in the atmosphere on. Greenhouse effect: carbon dioxide warming the lower atmosphere, then. Lower layers of atmosphere are more dense than upper layers which water vapour condenses and forms a small water droplet surface. Electromagnetic radiation: energy moving from the sun to earth. Frequency: the number of waves that pass a certain point every second. Electromagnetic spectrum: electromagnetic radiation exists at many different wave lengths (gamma rays, x-rays, uv, infrared, microwave, radio waves, long radio waves) Air pollutants surface through natural or human activities.
