What is the chief component of the Venusian atmosphere?Group of answer choiceshydrogennitrogencarbon dioxidesulfuric acidoxygen

The chief component of the Venusian atmosphere is carbon dioxide (CO₂), which constitutes about 96.5% of the atmosphere. This composition is significantly different from Earth's atmosphere, which is primarily nitrogen and oxygen. The high level of carbon dioxide on Venus contributes to an intense greenhouse effect, leading to surface temperatures that can exceed 900 degrees Fahrenheit (475 degrees Celsius).

Other components of the Venusian atmosphere include nitrogen (about 3.5%) and traces of other gases such as sulfuric acid, which forms clouds in the upper atmosphere. The presence of sulfuric acid is indicative of the planet's volcanic activity and contributes to the planet's harsh environmental conditions. In summary, while all the options presented play a role in the Venusian atmosphere, carbon dioxide is overwhelmingly the chief component.
