GEOG 3 Chapter Notes - Chapter 7: Black-Body Radiation, Shortwave Radiation, Surface Tension
Document Summary
Physical oceanography: the study of the physics of the world"s oceans. In chapter 6, we explored the properties, transformations, and exchanges of matter in the world ocean. In this chapter, we focus on the properties, transformations, and exchanges of energy, especially heat. Energy drives the movements and exchanges of matter. The law of conservation of energy states that energy can be neither created nor destroyed, but it can change forms. Radiant or solar energy: energy in electromagnetic radiation that comes from the sun, important in heating of earth, the ocean, and the atmosphere, and essential to photosynthesis. Kinetic energy: energy of motion of moving objects (= 1 2xmassxvelocity squared) Thermal energy or heat: energy of random motion of molecules, which results in the exchange of heat between objects. Chemical energy: energy stored within the chemical bonds of substances. Potential energy: energy related to the position of objects or the position of atoms in molecules.
