which category includes the terms carbon dioxide, methane, nitrous oxide, and cfcs?

solar radiation
systems

greenhouse gases

The correct answer is greenhouse gases.

Light from the sun passes through the atmosphere and most of the heat reaches to the earth surface and heat the Earth. After heating heat radiates back to the space.  The greenhouse gases which includes carbon dioxide, methane, nitrous oxide, and chlorofluorocarbons (CFCs) in the atmosphere absorb the radiated heat and release into the atmosphere causing global warming.

relative humidity, temperature and dew point -- are bound together in the mathematical relationship below. relative humidity changes when temperatures change. because warm air can hold more water vapor than cool air, relative humidity falls when the temperature rises if no moisture is added to the air. so i would say a

answer; i believe the correct answer is (a)0
