Biogeochemical Cycles Part 1: Major elemental cycles (carbon, oxygen, phosphorous, nitrogen, sulfur, hydrogen, water), chemical reservoirs, greenhouse gas effect, carbon dioxide (CO2), photosynthesis respiration cycle, how plants breathe oxygen at night, carbon burial and decomposition (oxidation), negative feedback, positive feedback, the use of carbon isotopes to track C burial rates throughout Earth history, using C isotopes to study early life on Earth and life on other planets and moons, using C isotopes to prove current climate change is man-caused by measuring the isotopic composition of atmospheric carbon dioxide derived from fossil fuels.
