timeline of important events

1. the Big Bang (~10-20 bya)
2. acreation of the Earth (~5 bya)
3. differentiation of layers
4. formation of oceanic/continental crust
5. Plate Tectonics; the rock cycle

• creation of atmosphere and oceans
• start of water cycle; phrase changes, energy clyclings, weathering/erosion, geochemical recycling

1. carbon cycle (biogeochemical cycling)

• organic reactions (photosynthesis/respiration)
• inorganic carbon (various reactions, see notebook)

water

• water cycle
  • mass + energy (phase transitions) + momentum => modelled by GCMs (general circulation models) whose main principals are conservation of those things
• properties of water
  • solvent -> geochemical cycles
  • heat capacity
  • temperature-density behaviour; thermohaline circulation
  • ice floats; water most dense at 4C (lake overturn)
  • flows as a liquid and solid

stuff from the video

• the "fatal flower": Dryas spp (mountain aves) which survives in cold, presumably living there 'cause it got warmer after gulf stream shut off due to glacial lake draining through st. lawrence (we now know drained to several places)
• subsidence from sea-level rise
  • weight from water
  • pumping out water
  • reducing sediment supply to built-on deltas

harrington thing

Your task is to prepare a 10-minute "show & tell" that (1) addresses the question of why Harrington chose that particular graphic (i.e., what was he trying to illustrate that he couldn't simply describe in words?), and (2) brings us up-to-date on how the situation has (or perhaps hasn't) changed since 1987 in our scientific understanding of your group's topic.
