MASS SPECTRA/3

QuestionAnswer
THE CLOUDS ABSORB MUCH OF IT AND THIS IS WHY ... CLOUDY NIGHTS ARE WARMER THAN CLEAR NIGHTS.
MOL ATMOSPHERE ABSORB CERTAIN FREQUENCIES OF THIS INFRARED RADIATION.(CALLED... GREENHOUSE GASSES).
THE MOLECULES ABSORBED INFRARED AND... GO INTO A HIGHER VIBRATIONAL ENERGY LEVEL, THEY THEN RETURN TO GROUND STATE BY EMITTING RADIATION OR THROUGH COLLISION.
COLLISION CONVERTS ENERGY INTO HEAT SO SOME RADIATION EMITTED BY EARTH... IS RE-RADIATED BACK TO EARTH OR TRAPPED AS HEAT AND DOESN'T; ESCAPE TO SPACE.
WATER VAPOUR IS ANOTHER ... IMPORTANT GREENHOUSE GAS. IT IS ESTIMATED THAT NEARLY 95%. OF RADIATION ABSORBED BY ATM IS ABSORBED BY WATER VAPOUR.
SO WHY NIGHTS IN DESERT ARE SO COLD... COZ LITTLE WATER VAPOUR IN AIR.
LEVEL OF C02 HAVE BEEN RISING SINCE... INDUSTRIAL REVOLUTION, AND STILL INCREASING.
HOW MANY PPM... TODAY WE HAVE 380PPM OF C02 IN THE ATMOSPHERE.
EVERY YR THE MASS OF C02 PRODUCED BY BURNING FUEL INCREASE BY ... 1 BILLION TONNES.
OTHER GASES THAT ABSORBED INFRARED ... ARE METHANE , HCFC AND CFCS, AS WELL AS OXIDES OF NITROGEN. APART FROM THE HALOGENATED HYDROCARBONS.
INCREASING DUE TO HUMAN ACTIVITY EFFECTS ARE... ICE AGES GLACIERS SWEPT BACK AND FORTH.
NATURAL AND ANTHROPOGENIC SOURCES OF ... GREENHOUSE GASES.
THERE IS NATURAL BALANCE BETWEEN ... PRODUCTION AND RELEASES OF C02.
ANIMALS AND PLANTS CONVERT CARBS INTO... C02 (RESPIRATION) AND PHOTOSYNTHESIS.
THE SEA ABSORBS... C02
CO2 IN RELEASED BY ... VOLCANIC ACTIVITY INCLUDING HYDROTHERMAL EVENTS DEEP IN OCEAN.
SHELLFISH STORE LARGE AMOUNTS... OF CO2 AS CACO3 WHICH FALLS TO OCEAN FLOOR WHEN DIE.
DURING CARBONIFEROUS PERIODS, C02 WAS... LOCKED UP AS OIL,COAL,FOSSIL FUEL.
WHEN BURNT FOSSIL FUELS' RELEASED ... THE C02 THAT HAD BEEN REMOVED BY PHOTOSYNTHESIS MANY YEARS AGO.
DURING THE INDUSTRIAL REVOLUTION MORE C02,CAUSING THE CONC OF C02 IN SEA AND ATMOSPHERE TO RISE.
THIS INCREASE THROUGH HUMAN ACTIONS IS CALLED... ANTHROPOGENIC ACTIVITY.
METHANE IS PRODUCED... NATURALLY AND ANTHOPOGENICALLY.
ANAEROBIC DECOMPOSITION OF VEG MATTER PRODUCES... METHANE.
AGRICULTURE IS A SOURCE IT’S PRODUCED BY... FLOODED RICE FIELD AND BY COWS AND SHEEP AND DECAY OF ORGANIC MATERIAL IN LANDFILL SITES.
