From Sun to Earth’s Atmosphere
Part I. Energy produced from the innards of the Sun until it reaches
Earth.
Matter and energy are

electromagnetic radiation through a medium.
Scattering is the redirection of
radiation to different directions by gas molecules.The shorter the wavelength, the
greater the scattering.
