conclusion

A

Anaerobic: without oxygen

C

Chemical Energy: energy stored between the bonds of molecules

E

Electron: one of the three particles that make up an atom. Electrons have a negative electrical charge

G

Gamma Radiation: high energy, short wavelength electromagnetic radiation emitted from the nucleus of an atom

Generator: connected to a turbine, a generator will convert mechanical energy to electrical energy

Greenhouse Gases: refers to those gases which trap heat with in the atmosphere, such as carbon dioxide

H

Hydrocarbons: substances consisting of hydrogen and carbon. Mainly refers to fossil fuels.

K

Kinetic Energy: the energy of an object due to its motion. Kinetic energy depends on the mass and velocity of an object

L

Law of Conservation of Energy: energy cannot be created or destroyed; it can only be converted from one form to another

M

Mantle: refers to the layer under the Earth's crust and above the Earth's outer core

Mechanical Energy: a combination of potential and kinetic energy.

N

Neutron: one of three basic particles making up an atom. Its mass is about the same as a proton. Neutrons have no electrical charge (considered neutral)

P

Photons: "packets" of light

Photosynthesis: process of using energy in sunlight to convert water and carbon dioxide into carbohydrates and oxygen.

Plankton: tiny animal and plant life drifting in water

Potential Energy: the energy stored in an object due to its position. A raised object will have potential energy. Potential energy is dependant on the mass and height of an object

Proton: One of the three basic particles making up an atom. Protons have a positive electrical charge

T

Turbine: a machine consisting of a bladed wheel connected to a shaft. Pressure and kinetic energy from fluids or steam are converted to mechanical energy through a turbine

V

Voltage: electrical potential; the measure of the difference in electrical energy between two points. Voltage is measured in Joules per Coulomb.
