GEOG 2051 Study Guide - Midterm Guide: Milankovitch Cycles, Eutrophication, Accumulation Zone
Document Summary
Outputs: outgoing energy the earth gives off. Equator and poles are connected in climate. Warm air masses from the tropic to the north: hurricanes carry huge amounts of energy from the equator to northern or southern hemisphere. As powerful as multiple atomic bombs: ocean gyres. Transports energy and influences climate: climate history, for much of earth"s history, temperatures have been 8-10 degrees celsius above what they are now. But, working their way to the present, temperatures have gotten cooler, while fluctuating temperature the whole time. Temperatures got cold enough for an ice age large portions of continents covered in ice sheets: quaternary. Glacial: climate cold enough for ice sheets to form. Interglacial: climate too warm for ice sheets to form. Co2 is a greenhouse gas then bounces back the earth"s output heat and heats up things: milankovitch cycles, orbit shape. Going from circular to elliptical every 100,000 yrs.
