GEOG 2050 Chapter : Ch 5
Document Summary
3/13/2013 12:04:00 am: last chapter: sw remains constant, temp: avg kinetic energy level of molecules, heat: flow/transfer of energy from areas of high to low concentration/temp. 32 degrees freezing pt numbers built off older scale. Absolute zero: pt where molecules of substance have no energy in them. Size of units are same as celsius, values equal just offset. Liquid/glass thermometer: alcohol inside, put into substance hotter than thermometer, molecules bounce against molecules in glass and push them apart so the liquid rises/lowers. Insolation: how much energy given, determined by latitude. 30 degrees north equator: market increase in seasons. 56 degrees: less seasonality, edge of ocean-moderates climate, gulf stream brings warm weather. 45 degrees nrth: increase in seasons, brief warm summers, long winters. Temp cntrl: cloud cover: moderates (reduces temp range) climate. Temp contrl: movement of ocean currents: ocean currents: determine weather. Temo contrls: continentality (land/water heating diff) and mixing.
