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.
Venus has an extremely dense atmosphere consisting mostly of Co2. It has a heavy sulphur enriched cloud base, which actually precipitates sulphur dioxide rain. However, becaus â¦ e of the temperature of the surface, these droplets vaporise before reaching the surface.
