definitions Flashcards
any natural material that is used by humans, such as water, petroleum, minerals, forest, and animals
Natural Resource
a natural resource that can be replaced at the same rate at which the resource is consumed
Renewable Resource
a resource that forms at a rate that is much slower than the rate at which it is consumed
Nonrenewable Resource
the process of recovering valuable or useful materials from waste or scrape; the process of reusing some items
Recycling
a nonrenewable energy resource formed from the remains of organisms that lived long ago
Fossil Fuel
a liquid mixture of hydrocarbons that is present in certain rock strata and can be extracted and refined to produce fuels including gasoline, kerosene, and diesel oil; oil.
Petroleum
flammable gas, consisting largely of methane and other hydrocarbons, occurring naturally underground (often in association with petroleum) and used as fuel.
Natural Gas
a combustible black or dark brown rock consisting mainly of carbonized plant matter, found mainly in underground deposits and widely used as fuel.
Coal
Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air.
Acid Precipitation
fog or haze combined with smoke and other atmospheric pollutants.
Smog
the energy released during nuclear fission or fusion, especially when used to generate electricity.
Nuclear Energy
the energy released during nuclear fission or fusion, especially when used to generate electricity.
Chemical Energy
Solar energy is radiant light and heat from the Sun that is harnessed using a range of ever-evolving technologies such as solar heating, photostatic, solar thermal energy, solar architecture, molten salt power plants and artificial photosynthesis
Solar Energy
Wind energy (or wind power) refers to the process of creating electricity using the wind, or air flows that occur naturally in the earth’s atmosphere. Modern wind turbines are used to capture kinetic energy from the wind and generate electricity.
Wind Power
Hydroelectric energy, also called hydroelectric power or hydroelectricity, is a form of energy that harnesses the power of water in motion—such as water flowing over a waterfall—to generate electricity. People have used this force for millennia.
