The Atmosphere of Venus The atmosphere of Venus is mostly carbon dioxide, 96.5% by volume. Most of the remaining 3.5% is nitrogen. Early evidence pointed to the sulfuric acid content in the atmosphere, but we now know that that is a rather minor constituent of the atmosphere. The mass of the Venus atmosphere is about 90 times that of the Earth's atmosphere. 90% of the Earth's atmosphere is within 10 km of the surface, whereas you have to go to 50 km to capture 90% of the atmosphere of Venus. The clouds of Venus may extend from about 50 to 70 km and may be divided into three distinct layers.
The planet s burning temperatures are greatly a result of the planet s atmosphere. The planet s atmosphere is made up of thick yellow clouds that cover up the planet s surface. Similar to the moon, Venus is a plain rock. The poisonous atmosphere would instantly kill off any breathing creature that would dare enter the planet. Also, the greenhouse effect is strongest in Venus out of all the planets. This intense heat also comes from the clouds that make Venus s surface invisible. These clouds are mostly made up of carbon dioxide, which makes a greenhouse effect that traps the Sun s heat.
