what is greenhouse effect
Answers
The greenhouse effect is a process that occurs when a planet's atmosphere allows unhindered radiant energy from its sun to heat the planet's surface, but then hinders the radiant heat from the surface from passing to space until the surface warms more than it would have done without the atmosphere. More specifically, most sunlight passes through the atmosphere to reach the Earth's surface, heating it. The same amount of energy must then radiate back into space, but this lower frequency heat is absorbed in the atmosphere by greenhouse gases such as carbon dioxide, methane and water vapor, and by clouds, so the surface warms until a higher layer of the atmosphere radiates all the energy. The greenhouse effect mainly occurs because heat makes all gas molecules with three or more atoms vibrate and rotate faster, thus absorbing some heat and re-radiating it in all directions.
