Carbon cycle:  movement of carbon from solid to liquid to gas and from rocks to water to air to organisms

Coal: solid fossil fuel formed from the partially decomposed remains of plant matter, primarily

Conduction: heat transfered via direct contact from an object with a higher temperature to lower

Crude oil: mixture of many different hydrocarbons

Fossil: remains from a living creature that become a rock

Fossil fuels: energy sources that form from fossils and are burned to create energy (e.g. coal, oil, natural gas)

Greenhouse effect: atmosphere acts like a "blanket" trapping in heat and keeping temperatures warm

Greenhouse gases: gases in the atmosphere that help absorb and trap heat, including carbon dioxide and water vapor

Hydrocarbons: materials that are crushed under tremendous heat and pressure. They can be soild (coal), liquid (oil) or gas (natural gas)

Natural gas: made of primarily the hydrocarbon methane gas

Nonrenewable resources: resources that are finite and, for all practical purposes, can be used up completely

Nuclear energy: energy released from the splitting of an atom

Oil: liquid fossil fuel 

Radiation: light/heat transfered between sun and Earth

Renewable resources: energy sources that are abundant and can replenish themselves
