Answer:

The chief component of the Venusian atmosphere is carbon dioxide (CO2). Venus has an extremely thick atmosphere composed mostly of carbon dioxide, with small amounts of nitrogen, sulfur dioxide, and other gases. The atmosphere is so dense that the surface pressure on Venus is about 90 times that of Earth's surface pressure. This makes Venus's atmosphere extremely inhospitable to human life, with temperatures hot enough to melt lead and a thick layer of sulfuric acid clouds that completely obscures the planet's surface. The thick carbon dioxide atmosphere also contributes to the planet's runaway greenhouse effect, which causes the surface temperatures to be much hotter than they would be otherwise.
