Energy+in+the+atmosphere

__**Energy In The Atmosphere**__ Energy in the atmosphere comes from clouds, dust in the air, gases, and Earth's surface, and 30% is reflected back into space. About 20% of the sun's energy is absorbed by clouds and gases. About half of solar energy passes through the atmosphere and the surface absorbs it. Primarily energy heats the atmosphere that is reradiated by earths surface. Solar energy has much of is energy in the visible spectrum. Energy that is radiated back into the atmosphere is mostly infrared radiation. Water vapor and carbon dioxide allow visible light to pass through but most infrared radiation is absorbed back to earth's surface which turns into the green house effect.

The green house effect is important because without it the earth would be much cooler than it is. The green house effect works when earth's surface is heated and energy is radiated back as infrared radiation. Some radiation is absorbed by gases in the atmosphere, this process which gases hold the heat in the air is the green house effect.
 * __The Green House Effect__**

Radiation heats the land and water which radiates back into the atmosphere. Radiation from the sun heats earth's surface then radiates heat skyward.

This topic related to heat transfer because it explains how heat is transfered from the sun to earth's atmosphere through the green house effect. This topic is important because it explains how our atmosphere work with energy. media type="google" key="4862688988015294183



__**Conclusion**__ What we thought was interesting was how earth's atmosphere is heated by the green house effect. What was suprising was that heat is absorbed by land and water and also how much is absorbed through energy and heat.
