Atmosphere

THE ATMOSPHERE IN BALANCE 17.1  ATMOSPHERE - A MIXTURE OF GASES CALLED AIR, THAT SURRONDS THE EARTH –EARLY ATMOSPHERE INFLUENCED BY VOLCANISM (CO 2, H 2 O, SO 2 AND N) –TODAY 99 % NITROGEN AND OXYGEN AND 1% CO 2, ARGON OTHER GASES AND DUST –SOME GASES LIKE H 2 O VAPOR AND CO 2 CHANGE FROM PLACE TO PLACE AND TIME TO TIME

 There are many different types of gasses in the atmosphere  They include nitrogen, oxygen, argon, carbon dioxide and other noble gasses  The gas that is most abundant is nitrogen

RECYCLING ATMOSPHERIC MATERIALS H2OH2O O2O2 CO 2 H2OH2O O2O2 H2OH2O H2OH2O

A DELICATE BALANCE  RECYCLING IN THE ATMOSPHERE MAY BE DISRUPTED BOTH NATURALLY AND BY HUMANS –CO 2 AND GLOBAL WARMING –ENERGY BUDGET
