GEOL 102 Study Guide - Planetary Differentiation, Archean, Earth Structure
Document Summary
Describe the process, product, importance, and any unresolved issues regarding. That world contained what was believed as the early atmosphere, no oxygen. The fluid turned pinkish orange, nutrients self-organized into 23 amino acids. Describe, in as much detail as possible, the relationship between photosynthesis, atmospheric o2, atmospheric co2, and the increased complexity of life on earth. You start with photosynthesis - byproducts = oxygen and organic matter. If the organic matter is buried then the oxygen stays in the environment, increasing the oxygen levels. Atmospheric co2 will decrease as its used in photosynthesis. More oxygen in the environment allows organisms to grow more complex. The earliest multicellular life: (a) first appear in the archean (4. 5-2. 5 billion years ago) **(b) required more available oxygen than unicellular life (c) were composed of prokaryotes (d) all of the above. Evidence that the earliest life on earth was thermophilic comes from:
