Document Summary
Types of energy potential energy stored by virtue of position chemical photosynthesis nuclear fission splitting atoms into smaller parts nuclear fusion combining nuclei to form large rnucleus sun kinetic energy of motion thermal energy of heat or motion electrical charged particles radiant energy from the sun. > absolute zero ( 273deg. c) radiant energy travels in electromagnetic waves that vary in wavelength and frequency travels at the speed of light in a vacuum no particles for energy to run into goes extremely fast frequency waves per second measured in units of hertz 1 hz = i oscillation wavelength length of one cycle period duration of 1 cycle p=1/f frequency # of waves per period electromagnetic radiation spectrum radio waves longest wavelengths. Key concepts: ozone layer naturally occurring biological man made atmospheric pressure noctilucent clouds exosphere heterosphere homosphere thermosphere/pause mesosphere/pause stratosphere/pause troposphere/pause lonosphere ozonosphere.
