Document Summary
Q = p e, q discharge/runoff. Low peaks are deserts (importing water or mining groundwater to supply human need) Extreme ends are also deserts (90n and 90s) Summer epilimnion layer (topmost layer where it interacts with the atmosphere), hypolimnium (bottom most layer), metalimnion (middle layer where the temperature of water changes very quickly) Fall fall turnover and the water column mixes by a storm. Winter 4 degree water is the densest, ice floats as it is less dense and insulates lake. Spring surface temp warms, turns over in spring, including great lakes (dimitic) African lakes permanently stratified including big lakes, no nutrient and o 2 cycling. Water properties hydrogen bonding causes water to boil at higher temps than expected. Lone pairs of electrons cause the molecule to bend. Electron density contours: shows where electrons are present most of the time.
