Methods of Heat Transfer QuickTimeª and a TIFF (Uncompressed) decompressor are needed to see this picture. Conduction: heat is transferred directly from molecule to molecule. This is most important in solids. Convection: heat is transferred as volumes of molecules move together. This is most important in fluids. Radiation: heat is transferred directly by electromagnetic waves. Sunlight is a good example.

Effects of Albedo Overall, 30% of sunlight reaching the Earth’s surface is reflected directly back into space. More sunlight is reflected from the Earth’s surface at high latitudes than low latitudes because of the angle of incidence. Albedo indicates what percentage of light will be reflected from a surface.

    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.
