GEOL 1030 Lecture Notes - Lecture 10: Dynamic Equilibrium, Mineralized Tissues, Radical Change
Document Summary
Earth"s atmosphere has had a radical change co 2 -rich to co 2 -poor. Venus and mars have has little change. Incoming visible light is absorbed at short wavelengths atmosphere warms heat is given off as infrared in longer wavelength radiation this outgoing radiation is trapped by the atmosphere. Produced by glass or by gases in the atmosphere (co 2 , h 2 o, ch 4 and. Earth"s greenhouse effect has weakened life processes decreased atmospheric co 2 (0. 04%) Life has always been in dynamic equilibrium with the greenhouse effect we are now changing the atmospheric co 2 concentration. Burning of living plants and dead plants (coal, oil, natural gas) Small enough amount, but enough to trigger climate change. Before life, atmosphere was filled with co 2 . Co 2 is chemically tied up in limestone (caco 3 ; reefs, shells, mineralized tissue of invertebrates, and algae).
