Troposphere The atmosphere is divided into a number of sections depending on altitude. The densest part of the atmosphere, the troposphere , begins at the surface and extends upwards to 65 km. At the furnace-like surface the winds are slow, [1] but at the top of the troposphere the temperature and pressure reaches Earth-like levels and clouds pick up speed to 100 m/s. [3] [12] The atmospheric pressure at the surface of Venus is about 92 times that of the Earth, similar to the pressure found 910 metres below the surface of the ocean. The atmosphere has a mass of 4.8×10 20 kg, about 93 times the mass of the Earth's total atmosphere. [1] The pressure found on Venus's surface is high enough that the carbon dioxide is technically no longer a gas, but a supercritical fluid . The density of the air at the surface is 67 kg/m 3 , which is 6.5% that of liquid water on Earth. [1] The large amount of CO 2 in the atmosphere together with water vapour and sulphur dioxide create a strong greenhouse effect
