Document Summary
90% of total mass of atmosphere and most of water vapour, clouds, air pollution. At the equator the tp (tropop) 15-17 km high. At the poles tp 9-12 km high. Ozone forms by the dissociation of molecular oxygen (o2) to form. Atomic oxygen (o) by radiation with wave lengths <0. 2 ultra violet. What is the link between global warming and the ozone hole. Atmosphere and surface energy balances: the uneven distribution of energy is responsible for driving earth"s dynamic. Transmission of energy (the passage of energy through atmosphere or systems: have excess incoming energy. Changing direction of light"s movement, without altering its wavelengths. Change in speed and direction of light. Whenever light passes from one medium to another (e. g. empty space to the atmosphere or from air to water) there is a change in speed and direction. Link between path length, scattering, blue skies and red sunsets. Moon has around 60 or 16% albedo (i think its 60)
