Detailed explanation-1: -For example, Venus and Mars have more than 98% of their atmosphere in carbon dioxide and nitrogen, while Earth has 99% of its atmosphere in nitrogen and oxygen.

Detailed explanation-2: -Venus has the most massive atmosphere of the terrestrial planets, which include Mercury, Earth, and Mars. Its gaseous envelope is composed of more than 96 percent carbon dioxide and 3.5 percent molecular nitrogen.

Detailed explanation-3: -Venus today is a hellish world. It has a crushing carbon dioxide atmosphere 90 times as thick as Earth’s. There is almost no water vapor. Temperatures reach 864 degrees Fahrenheit (462 degrees Celsius) at its surface.

Detailed explanation-4: -Carbon dioxide is common on Venus. “Presently, the atmosphere of Venus is mostly carbon dioxide, 96.5 percent by volume, ” said lead study author Dima Bolmatov, a theoretical physicist at Cornell University in Ithaca, New York..

Detailed explanation-5: -Because Venus has such a dense atmosphere which is some 100 times thicker than the earth’s. Evidently, Venus is sufficiently close to the Sun that the little carbon dioxide it had in its early, Earth-like atmosphere caused the surface to warm up and leach out more carbon dioxide into the atmosphere.
