-more prone to errosion
-evaporation= liquid ---> gas (more salty)
-freezing= liquid ---> soild (more salty)
-melting= solid ---> liquid (less salty)
* could have 2-3 processes at once
* less salinity in tropics
-temp. + salinity = DENSITY
+ vertical currents= density differences
+ surface currents= temperature difference
-mostly caused by differences in temp and salinity (gives density diffs)
-caused by the wind.
= daily cyles related to the rotation of the Earth
-periodic rise and fall of the waters in the ocean
-greatest diff. between high and low tide
-high tide always follows the moon
-least amount of diff. between high and low tide
-is equal to half of the wavelength
-h2o less than wavebase

Tim, University of Florida
"StudyBlue provides way more features than other studying apps, and thus allows me to learn very quickly! I actually feel much more comfortable taking my exams after I study with this app. It's amazing!"
Jennifer, Rutgers University
"I love flashcards but carrying around physical flashcards is cumbersome and simply outdated. StudyBlue is exactly what I was looking for!"
