Irvine disappear, first being successful was hillary and norgay. Since then there have been 3000+ climbs. First women to climb was in 1975 (tabei) Most summits: done by ang rita sherpa. Gases that make up the atmosphere; nitrogen, oxygen and argon, other components are only 1% Atmo from greek word meaning water vapour. Layer of gas that covered the earth, held in place by gravity. Troposphere - where life on earth occurs, heated from below the earth, 75-80% of earth"s. Stratosphere - 2nd major layer (15-50 km above the surface), air is thin, contains o3 mass is in troposphere (this is why pollutions do not move around much in the stratosphere) Energy passing through the atmosphere drives ecological systems.
