how does the atmospheric pressure on the surface of venus compared to that on earth
The atmospheric pressure at the surface of Venus is about 90 times that of Earth's (90 atm). This atmosphere consists mainly of carbon dioxide, which is a gas that is not breathable.In addition, the clouds of Venus contain drops of sulfuric acid, a poisonous chemical.ecause of Venus' heavy atmosphere, the planet's surface pressure is very high. Pressure is defined as the weight of the atmosphere pressing down on you per unit area. On Earth, we don't notice the air pressure at all. The thick atmosphere on Venus would make it difficult to see objects very far away from you.
