How could a scientist know if Venus had weather?
look at its atmosphere
How do you know that Venus' has an atmosphere?
It's been known since the 18th century that when Venus moves in front of the sun, then translucent fringes can be seen around the planet from which it was suggested that Venus had an atmosphere. Robot ships have entered the Venusian atmosphere several times and we now know the composition and density of the atmosphere (it's mainly carbon dioxide).
Why is Venus orange?
Venus appears in those colors for the same reason Earth looks blue and white: the contents of its atmosphere. Earth's atmosphere is composed mainly of nitrogen and oxygen, with a lot of water vapor. Venus's atmosphere is composed of greenhouse gases, like carbon dioxide and methane (the same gas that's in farts =O ). The colors reflect the visible light spectrum due to these elements.
Do any other planets have oxygen?
Earth is the only known planet with an oxygenated atmosphere.
Why is Venus hotter then earth?
Two reasons I know of; Venus is closer to the Sun than the Earth is. Venus has a very thick CO2 atmosphere that captures much of the solar heat.
How do scientists know that there is a greenhouse effect occurring on Venus?
They know it because the atmosphere on Venus is 93% carbon dioxide and the surface temperature is between 400 and 500 degrees C.
What object is the brightest in the night star for its thick atmosphere?
You put in the Planet venus section, don't you already know the answer, dummy, it's PLANET VENUS.
How much breathable air is on Venus?
The atmosphere of Venus is not breathable by any life form that we know of. Our probes survive less than a minute on the surface.
What is Venus' environment?
Venus' environment is very harsh. It is primarily carbon dioxide with a little nitrogen thrown in. There is a runaway greenhouse effect, and the average temperature is actually hotter than Mercury. Above the carbon dioxide layers, there are clouds of sulfur dioxide and sulfuric acid, contributing to the greenhouse effect. Average temperature is 460 C, or 860 F.
How much breathable air is on Venus' surface?
The atmosphere of Venus is not breathable by any life form that we know of. Our probes survive less than a minute on the surface.
Which two planets are mostly composed of methane and nitrogen?
The two planets that are mostly composed of methane and nitrogen are Uranus and Neptune. These gas giants have thick atmospheres made up primarily of methane and nitrogen, with smaller amounts of other gases such as hydrogen and helium.
Is there anything on Venus?
"Anything" is a broad category. Yes, there are many things on Venus. No, there is no life, as we know it, on Venus. Venus' atmosphere is 95% carbon dioxide with 5% nitrogen, with heavy clouds of sulfur dioxide and sulfuric acid. The average temperature on Venus is 460 C (860 F), hotter even than Mercury.
