Remote sensing - Study guides, Class notes & Summaries

hotosynthesis - Conversion of light energy from carbon dioxide and water to produce chemical energy and oxygen Color Theory - Color theory also involves the messages colors communicate; and the methods used to replicate color. How humans perceive color; and the visual effects of how colors mix, match or contrast. 3 categories: primary colors, secondary colors and tertiary Law of Conservation of Energy - Energy cannot be created or destroyed, only changed from one form to another Law of Co...
