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.
â¢ Venus has essentially no ozone in its atmosphere. 6. Compared to the Earth's atmosphere, that of Venus has â¢ much lower temperatures (200 K), due to the dense cloud cover, and higher pressure (90 atmospheres). â¢ much higher atmospheric pressure (90 atmospheres) and temperature (750 K).
