Chemical Energy

1. Chemical Energy Potential energy stored in chemical bonds Application: The high-energy bonds found in food are broken down by your body and allows your body to obtain the energy to power its activities and functions

2. Chemical Reaction A reaction that occurs when atoms separate from molecules or recombine with other molecules Application: Through chemical reactions, the decomposition of certain chemicals can be seen such as the reaction between methane and air when it is burned

3. Chemical Weathering The breakdown of rocks and minerals by chemical reactions, the dissolving of chemical elements from rocks, or both Application: Alters primary minerals to form secondary minerals and ionic forms of their constituent chemical elements which could be essential nutrients for plants

4. Chemosynthesis A process used by some bacteria in the ocean to generate energy with methane and hydrogen sulfide Application: Bacteria that use this process form the base of a deep-ocean food web

5. Child Mortality Rate The number of deaths of children under age 5 per 1,000 live births Application: A leading indicator of the level of child health and overall development in countries.

6. Chlorofluorocarbons (CFCs) A family of organic compounds whose properties make them ideal for use in refrigeration and air-conditioning Application: Harm the atmosphere by reacting with sunlight and decomposing into separate chlorine atoms which breaks the bonds in a molecule of ozone

7. Chronic Disease A disease that slowly impairs functioning of an organism Application: Category in which diseases fall under.

8. Chronic Study An experiment that exposes organisms to an environmental hazard for a long duration Application: To examine the long-term effects of chemicals, including their effects on survival and their impacts on reproduction

9. Convention on International Trade in Endangered Species (CITES) A 1973 treaty formed to control the international trade of threatened plants and animals Application: To prevent illegal plant and animal trade

10. Clear-Cutting A method of harvesting trees that involves removing all or almost all of the trees within an area Application: Easiest harvesting method and most economical. Increases wind erosion and water erosion, which causes loss of soil and nutrients
