CO2
Venus has an atmosphere that is extremely dense and composed primarily of carbon dioxide, with pressure at the surface about 92 times that of Earth's. The atmospheric pressure and high temperatures on Venus would indeed crush and incinerate a human.
Greenhouse effect. The same effect that keeps Earth warmer than if there would be no atmosphere: without an atmosphere, the average temperature on Earth would be below zero Celsius.
Not if you were on the surface of Venus. Venus has a very dense atmosphere which would mean you wouldn't see any planets or stars. You might just be able to make out the shape of the Sun but not very well.
If Earth's atmosphere had as much carbon dioxide as Venus, the oceans would become very acidic, leading to the destruction of marine life and ecosystems. This would have a devastating impact on the planet's biodiversity and overall health.
Venus has an atmosphere that is extremely dense and composed mainly of carbon dioxide. The atmospheric pressure on Venus is about 92 times that of Earth's, which would crush a human due to the immense pressure.
Venus has an atmosphere, though the "air" is not the same as on Earth (and would, in fact, instantly kill you).
Not a lot! Early life transformed the atmosphere; removing much of the carbon dioxide, so without life Earth would probably have an atmosphere and environment like Venus.
Yes, the gravity on Venus is about 91% of the gravity on Earth. So, a human on Venus would not be significantly squashed by the gravity, but they would feel heavier than on Earth due to the increased gravitational force.
No. The atmosphere of Venus would kill you very quickly. At the surface, temperatures exceed 800 degrees Fahrenheit and pressure is more than 90 times that at sea level on Earth. The atmosphere itself is mostly carbon dioxide. So you would be simultaneously baked and crushed if you were to set foot on Venus.
Venus is mistaken to be classified as earth's "twin planet" its mainly because it is only a couple hundred kilometers smaller then earth. but it has a lot of differences. Venus is an extremely hostile planet for life to harbor. it has a thick atmosphere of sulfuric clouds that traps the heat in the atmosphere. If it is the "twin planet" of earth would it supposed to sustain life?
The strength of gravity on the surface of Venus is about 91% of what it is on Earth, so the gravity there would be quite comfortable. Unfortunately the surface temperatures and pressures produced by the atmosphere of Venus would kill a human very quickly.
Venus has a very thick atmosphere. Even though it is similar size to Earth, no one could survive on Venus' surface as the atmosphere has a much higher pressure meaning that we would be crushed and burned!
