rays - the region of energy in the electromagnetic spectrum from about
10-5 to 10-1 nm in wavelength; smallest wavelengths
and the most energy of any wave in the electromagnetic spectrum. (more)
climate change - the hypothesis that the known increase in greenhouse
gas concentrations has led and will continue to lead to changes in the
Earth's climate; also known as "global warming."
force - force exerted by a body as a result of its mass.
effect - the process of incoming short-wave solar radiation being
absorbed by the surface of the Earth and re-emitted as longer-wavelength
radiation, which is then absorbed, retained, and re-radiated by certain
gases in the atmosphere. The net result is a "warm blanket"
around the Earth that prevents sudden cooling and heating effects each
time the face of the Earth rotates away from or towards the sun. (more)
gases - gases in the atmosphere which absorb, retain, and re-radiate
energy in the infrared region. (more)
