Document Summary

The quality of energy/matter deteriorates over time (the law of increasing entropy: the energy cycle: solar energy in, earth energy emitted, solar energy reflected, hydrological cycle: storage, evaporation, precipitation, runoff/storage, biochemical cycles: chemical compounds cycling between subsystems, rock cycle: igneous (extrusive), metamorphic, sedimentation, metamorphic (back into crust) Global temperature in the mesozoic: divided into hothouse/icehouse: triassic early jurassic: warm and dry, interior of pangaea dry and arid, north and south of interior seasonal rainfall, poles" very humid, as tethys opens in jurassic, moistness increases, mid late jurassic: this continues, seasonal snow at poles but still very warm, late jurassic early cretaceous: coldest time of mesozoic, still warm by our standards, small permanent polar caps > glendonites/dropstones (rocks picked up by glaciers then dropped in water) found in nunavut, mid late cretaceous: high sea/co2 levels mean very hot, no ice (regulated by.
