 Ocean Distribution - 70.8 percent of surface covered by oceans, ppl that lived near mediterran. Thought that the  world was large landmasses surrounded by water - Oceans contain 92.7 % of all water on or near earths surface - 61% of northern hemisphere is ocean, 81% of southern is ocean Thermal  Transfer -radiation – electromagnetic propagation This manner of heat transfer requires no tangible, intervening medium to support  its transmission.  The amount of energy moved from one place to another is either regarded  as proportional to the amplitude of an electro-magnetic wave or the energy possessed by a  photon in the particle analogy to light.  Radiation exhibits a wave or particle nature  depending on the kind of   interaction it is having with a medium.  This duality was central to  the creation of quantum mechanics and the understanding of  black-body  radiation.   The  wave or particle energy is related to the temperature of the emitting body.    -conduction – movement through a medium or boundary Fourier’s Law of Heat Conduction The flow of heat at any location in a medium is directly proportional to the temperature  difference across that location, that is, proportional to the rate of temperature change at the  location. The physical mechanism affecting the flow of thermal energy is an exchange of kinetic  energy through collisions of warmer atoms or mole-culesor with those of lesser energy. - convection – mass movement due to density differences A fluid volume expands when it is heated and becomes less dense, that is, it has less  mass per unit volume.  When there is an energy source, a volume of fluid at (a) will be  heated, become more buoyant in the earth’s gravitational field than the surrounding  unheated fluid, and will rise (b).  The fluid will cool at the boundary of the fluid called an  energy sink (c) becoming more dense as a result and descend (d) to return, flowing back (e)

    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.
