Class 1 Sun drives four processes at Ocean surface : Used by plants for photosynthesis Reflected back out Warms surface water Drives evaporation- Causes HUGE sun energy, evaporation absorbs 540 calories per gram; condensation releases 540 calories per gram Light reflected back from seawater (why oceans are blue!) Changes in color with depth- Blue is the only color not reflected with depth, red is absorbed the most Basics of evaporation and heat- Heat is absorbed with evaporation and released with condensation, this is why Seattle is warmer than Montana Dynamics within oceans driven mainly by atmosphere processes Layers in Atmosphere- Troposphere (14KM), tropopause (18KM), stratosphere (50KM) and it contains our ozone layer

Unformatted text preview: Atmosphere gases, temperature, pressure: 78% nitrogen, 21% oxygen, 1%argon, 0-4% water vapor, .035% carbon dioxide Humidity=water present/max water air can hold, air can hold 1-3% humidity Sun energy on fixed Earth and spinning Earth Simple circulation in the atmosphere (2 cells)- Water evaporates on the equator and spreads toward the poles where it is cooled and rained/snowed out. The Hadley cells between 0-30 degrees latitude are subtropical highs and dry More complex circulation (6 cells, no rotation) Coriolis force/effect- Wind in northern hemisphere goes right while it goes left in southern hemisphere, Clockwise in northern hemisphere and counter clockwise in southern hemisphere As air sinks it becomes drier...

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
