GEOG 131 Chapter Notes - Chapter 2.0, 2.2, 2.5, 2.6: Advection, Electromagnetic Spectrum, Dominant Wavelength
Document Summary
The interaction of energy with the earth"s atmosphere and surface determines the climate, weather, and habitability of an area. Energy- capability of an object to do work: expressed at an atomic level by motions of atoms, molecules, and their constituent parts. Temperature- measure of the average energy level of its molecules and atoms. Potential energy- stored energy: energy that is not being expressed directly but could potentially be released. Cooling indicates a loss of energy whereas warming indicates a gain of energy. Electromagnetic radiation- energy radiated from charged particles and manifested as interacting electrical and magnetic elds. Direction of propagation- direction in which a wave is moving. Amplitude- height of the wave from trough to crest. Wavelength- distance between two adjacent crests (tops) or two adjacent troughs (bottoms) Frequency- number of waves per second passing a point. Fusion- protons and neutrons join together to produce larger particles. As an object increases in temperature, the object emits more energy.
