What causes extremely high temperatures on surface of venus?

Answer 1

Venus is the second-closest planet to the Sun, but it is hotter than Mercury, which is even closer.

The reason is the thick atmosphere of Venus, which is mostly carbon dioxide. This creates a "greenhouse effect", which is like a blanket on the planet, trapping infrared radiation which would normally radiate excess heat back into space. This makes the temperature hellishly hot, as high as 464°C (867°F). and this heat affects the entire planet, even at the poles and even at night.

Answer 2

Venus experiences very high temperatures because it is closer to the sun than the Earth, but it is also very hot on Venus because it is enveloped in a thick cloud of Carbon Dioxide, which causes a green-house effect on the planet, which keeps a lot of the heat on the surface from escaping the planet.

Answer 3

Sulfuric Acid clouds cause the high temperature on Venus.

Answer 4

Because the Atmosphere is so dense

Answer 5

It is the 2nd closest planet to the sun
