55054.Burning of fossil fuels
increased oxygen level
increases greenhouse gases
decreases greenhouse gases
increased ethane level
55056.Relative contribution of various greenhouse gases to total global warming will not be
CFCs – 14%
N2O – 12%
Carbon dioxide – 60%

55057.This statement is false about greenhouse effect
life on earth is possible due to greenhouse effect
greenhouse effect is a natural process that maintains earth’s temperature
increased emission of greenhouse gases is a natural process
increased emission of greenhouse gases in the atmosphere increases earth’s temperature
