They know it because the atmosphere on Venus is 93% carbon dioxide and the surface temperature is between 400 and 500 degrees C.
Earth mostly, but also Venus and Mars.
Just as the earth has naturally-occurring carbon dioxide in its atmosphere, so also does the planet Venus have naturally-occurring carbon dioxide in its atmosphere. Because the concentration of carbon dioxide is so high in the Venetian atmosphere, it has a more considerable greenhouse effect.
yes Venus experiences the greenhouse effect
Both Earth and Venus have increase temperature due to a greenhouse effect. Venus has a much stronger greenhouse effect than Earth does.
There is no bright sunlight on the surface of Venus. It's not really because of the greenhouse effect, even though Venus does have a big greenhouse effect.
EarthVenusMarsThe greenhouse effect occurs on every planet with an atmosphere (including Earth). On Venus, there is a runaway greenhouse effect causing temperatures high enough to melt lead.Mars has a greenhouse effect that is weak because of its thin atmosphere.
Venus has a runaway greenhouse effect that has boiled its oceans dry.
Only Venus and Earth have a greenhouse effect because they have a substantial atmosphere. Venus actually has a runaway greenhouse effect causing its surface temperatures to rise to 450 Celsius.
Venus. Similar to Earth in many ways, a runaway greenhouse effect is thought responsible for its 900°F (480°C) surface temperature.
Venus, due to its strong Greenhouse Effect.
The trapping of heat by the atmosphere of Venus is called the greenhouse effect, just as it is on Earth. Venus is the second closest planet to the sun and the temperature on the planet reaches 870 degrees Fahrenheit.
