Greenhouse Effect and Global Warming

Greenhouse effects show the increase in temperature as a result of the entrapment of heat energy

The short wavelengths of ______ emitted from the sun penetrate the glass. They are absorbed and re-emitted as long wavelength ______. These long waves cannot penetrate the glass and such remains trapped in the greenhouse.

Global warming involves greenhouse ______ acting as a glass layer. Carbon monoxide, carbon dioxide and methane are greenhouse ______ preventing the emergence of heat back into the atmosphere.
