Document Summary
3. 1 the hydrologic cycle: the hydrologic cycle exchanges water among reservoirs, small amount of freshwater available and most of it is unusable or unreachable, lots in. N and s: deep sea corals do exist (not in reefs) and have lived 4000 years, found close to nova. C: coral limited to tropical waters where minimum temperature doesn"t fall beneath. C: high temps are usually lethal (29 deg. Fpom washed down from the headwater streams and algae and aquatic plants. In eutrophic lakes oxygen depletion may occur at night as respiration continues in the absence of photosynthesis: depletion in winter under the ice of productive temperate lakes. In tropical lakes, water below the euphotic zone is often permanently depleted of dissolved oxygen: biology. Increasing temperatures will increase decomposition rates, and increase evaporation rates, reducing water outputs, can change plant transpiration rates: water movements, relatively still waters, water levels must be stable, if water table lowers, peats may dry up.
