Document Summary
Australia"s marine environment: ocean basins distributed asymmetrically about the world more in the, australia has a large jurisdiction over marine water than land. Australia"s marine environment outline: chemical & physical properties southern hemisphere. Hydrogen bonds strong: high heat capacity. Takes a lot of heat to raise the temperature. Not a lot of heat coming from the tropics due to cloud cover. 99. 6% comprised of: chlorine, sodium & magnesium, sulphur, calcium, Changes in salinity caused by: heat up water- water evaporated, more. Important for local global circulation & organisms: lowers freezing point. Seawater 3. 2% to 3. 7% salt salt (in hotter areas- equator- more sunlight). Convection cells: warmest in tropics, earth warmer around the equator hot air rises at the equator spreads out towards the poles convection cells (non rotating sphere) Coriolis effect: rotating earth, north hemisphere deflects to the right, southern hemisphere deflects to the left.
