Document Summary
Office hours: mon/tues 11:00 12:00 sw 563b. Ecology is scientific study of the distribution and abundance of organisms and the interactions that determine their distribution and abundance. Applied ecology is about getting organisms to survive so they can be used as a food resource in the winter. The scientific method: observation, hypothesis, evaluate hypothesis, next steps. Climate long term average of weather. Visible light goes back into the earth"s atmosphere. Lower transmission is ice age for atmospheric transmission. Ozone stops short wave uv and greenhouse gases trap heat (long wave) Insolation the amount of solar radiation reaching a given area (usually at noon because that is when it gets the most sun) 90 degree angle hitting the equator equinox. 23. 5 degrees n is summer solstice, 23. 5 degrees s is winter solstice surface winds are towards the equator. Uplift warm air is less dense so it rises. Subsidence creates bands of high pressure at 30on and 30os of equator creating deserts.
