Document Summary
Atmospheric carbon dioxide levels have therefore increased steadily through the period of monitoring. Kneeling curve: carbon cycle: intricately linked network of biological and physical processes that shuttles carbon among rocks, soil, oceans, air, and organisms. 25. 1: what processes introduce carbon dioxide into the atmosphere: Burning of fossil fuels: what process remove carbon dioxide into the atmosphere: That is why photosynthesis does not deplete the carbon dioxide in the air: except in a narrow band around the equator, photosynthesis is seasonal, with higher rates in the summer and lower rates in the winter. Respiration, in contrast, remains more or less constant through the year. Before keeling, no one systematically collected air samples. When the glacial ice forms in antarctica and greenland, t traps tiny bubbles of air. Each year, snowfall gives rise to a new layer of ice, and as. Midterm #2 notes layers accumulate through time their bubble preserve a history of the atmosphere.
