Document Summary

Final exam 40% (50% new material + 50% cumulative material) Outline: ocean geographic distribution, ocean water, wet and salty, waves, coastlines and storms, surface waves caused by wind, interactions with shoreline. Seawater covers 71% of earth"s surface in three huge interconnected basins: the pacific ocean, the atlantic ocean, the indian ocean. Pacific ocean + atlantic ocean + indian ocean = world ocean. The ocean is so unknown because the sun cannot penetrate the deep depths of water: so many places in the ocean that we haven"t explored. High heat capacity: the heat capacity prevent extreme temperatures; heat transfer by currents is large. High latent heat: latent heat acts as a thermostat; important in transferring heat and water to atmosphere. High surface tension: surface tension controls drop formation and such surface phenomena as capillary waves. High transparency: transparency is the absorption of infrared and ultra-violent radiant energy is large; absorption is visible-light radiant energy is small, making water colourless .
