Question

Green house effect is warming due to

(a) infra-red rays reaching earth

(b) moisture layer in atmosphere

(c) increase in temperature due to increase in carbon dioxide concentration of atmosphere

(d) ozone layer of atmosphere.

Answer 1

Answer (C) Increase in temperature due to increase in CO2 Concentration of atmosphere,

*the gradual increase in the overall temperature of Earth atmosphere due to the greenhouse effect,this effect is caused byincrease level of carbon dioxide and chlorofluorocarbon and other gases in the air,many of released by human activity,

*greenhouse effect with naturally occurring phinomenon that is responsible for heating of Earth's surface And Atmosphere.

greenhouse effect the average temperature at surface of earth would have been a Chilly -18°C rather than the present average of the 15°C,you may now the fate of the energy of sunlight that which is the outermost atmosphere clouds and gases reflect about one-fourth of the incoming solar radiation,But increase level of greenhouse gases has lead to considerable heating of the leading to global warming during the past century the temperature of earth has increased by 0.6°C moist and rise in temperature is leading to deleterious changes in environment,

***Various greenhouse gases total global warming

N2O=6%,CFCs=14%,Methane=20%,Co2=60%
