Extracting, processing, and using nonrewnewable mineral and energy resources. Disturbed land, mining accidents, health hazards, mine waste dumping, oil spills, and blowouts, moise, ugliness, heat. Solid waste, radioactive material, air, water, and soil pollution, noise, satefy and health, hazards, ugliness, heat. Transportation or transmission to individual user, eventual use, and discarding. Noise, ugliness, thermal water pollution, pollution of air, water and soil, solid and radioactive waste, safety and hazards. A substance consisting of atoms which all have the same number of protons. Elements are chemically the simplest substances and hence cannot be broken down further using chemical methods. Elements can only be changed into other elements using nuclear methods. Resources are formed and concentrated by either the sun"s energy or earth"s internal energy.
