Presence of the greenhouse gases as the carbon and the water vapor that make up over most of the greenhouse of the earth and the presence of the clouds in the surface of the earth absorbs most of the infrared waves and thereby it provides a blanket to the earth and an average temperature of the earth is about 1000 millibars and is about the 15 degrees which equate to the 288K and thus is without the greenhouse effects.
<u>The planet of Venus has no atmosphere due to the low attraction of the molecules of the air and they were blown away by the sun stroma and have 96.5% carbon dioxide and have 3.5% of the nitrogen.</u>
