A lot. Venus' atmosphere is 80 times thicker than ours, and over 90% of it is CO2. That's way more carbon dioxide than we have. Scientists think a runaway greenhouse effect in Venus' distant past is responsible for this, which forces us to scrutinize our own abuse of carbon dioxide! The surface of Venus is a ridiculous 800 degrees Celsius as a result of that greenhouse effect (and of course, Venus' proximity to the sun.)

Which substance was not present in Earth's primitive atmosphere?
Oxygen was not found in the atmosphere of primitive Earth. It is so reactive that it became locked up in compounds at the time of Earths formation. These compounds were varied, but the bulk of them were mineral oxides, silicates, carbon dioxide and water. Free oxygen entered the atmosphere only after the development of blue-green algae, which produced oxygen from carbon dioxide.
How much carbon dioxide is given out from different flavors of ice cream?
One
How does earth atmosphere make conditions on earth on suitable for living things?
REASON ONE: ATMOSPHERE Earth has a breathable atmosphere. Oxygen is the gas that is required for the life of most creatures. This is present in Earth's atmosphere, along with nitrogen, and in water, along with hydrogen. Oxygen is constantly put into the atmosphere by plants and trees. Fortunately, Earth's atmosphere does not contain much carbon dioxide, a poisonous gas which makes up most of the atmosphere of planets like Venus and Mars. In densely-populated areas, carbon dioxide is more present. This is because cars and factories produce it. This causes the air to be polluted. The Earth's atmosphere is kept on the planet by its pull of gravity. Mars and Mercury are too small to keep atmosphere. As a result, Mercury has no atmosphere, and Mars' atmosphere is very thin, containing gases which have not managed to escape into space yet. Earth's atmosphere is thick enough to prevent poisonous rays of radiation from getting through it (this is what has happened on Mars).
How does Earth's atmosphere compare to the atmospheres of Mars and Venus?
Okay first of all mars does not have life 2ndly mars is the 4th planet earth is the 3rd planet mars is mostly red and earth is mostly blue there is some but there are alot moreThe difference between them is that Earth is larger and Mars does not have qualities for life to sprout.71% of Earth's surface is water. Mars has no liquid water, but the Phoenix Mars Lander scooped up soil and ice.Mars gravity is 2.7 times less than that of Earth. Mars has 2 moons and it's atmosphere is 95% CO2 with a tiny bit of nitrogen, argon, oxygen, and carbon monoxide.Earth has 1 moon and has a lot of nitrogen and some oxygen and others (tiny bits of argon and carbon dioxide).(Also, our deserts are hot in the daytime and cold at night. Mars's deserts are freezing and airless.)The biggest difference is that Earth has advanced life forms, Mars does not.Mars is smaller than earth with less gravity. It also has a very thin CO2 atmosphere where Earth has a Nitrogen Oxygen atmosphere that is much thicker. Mars is also very cold while Earth is warm.* Earth is almost twice the diameter of Mars.Nearly 70% of Earth's surface is liquid water, while Mars has none.The sun warms the Earth to more the 100oF; on Mars the temperature barely goes above the freezing mark.Earth has an atmosphere breathable by humans. Mars has virtually none, and it is composed almost entirely of toxic gases. IIRC, Mars is about 1 1/2 time farther from the sun than Earth; and is about 1/2 the size, and 3/4 the density.It's surface is largely iron oxide, which gives it its reddish color. There is no liquid water (there is ice at the poles). Because is it has a much thinner atmosphere, and is farther from the sun, it is much colder.Astronmers speculate that Mars was once much closer to the sun and was more "earthlike," but gradually moved farther away, resulting in its present state.
How was oxygen introduced into Earth's atmosphere?
Oxygen was not necessarilly "introduced" to the Earth. Many people have a hard time understanding that the ozone layer that surrounds the Earth is not "holding in" our breathable atmosphere. Air is our atmosphere. Air has "weight", believe it or not. The Earth has "gravity". Air acts much like water in that respect, atmosphere will be "pulled" to the Earth by gravity. It is believed that the chemical reactions on the Earth, like magma from volcanoes, has created a lot of carbon dioxide. Thus life forms as plants grew. As we all know, plants live on carbon dioxide and it grew and encouraged growth of other life forms. Other life forms produced more chemical reactions and by-products such as carbon dioxide, and nitrogen when the life form died and decomposed. Thus creating our atmosphere. There is also the concept that the Big Bang scattered the components necessary for the planets in the system and that the Earth "accumulated" it while revolving aroudn the Sun. This is very plausible considering there is a lot of ice in outer space and when it impacts a surface, like the Earth, the ice melts and creates water, which is made of hydrogen and oxygen. Remember also that life "came from the pre-historic oceans as we know it". So, long story short, oxygen was not necessarilly "introduced" to the Earth as much as it was "produced" also.
What planet's atmosphere is most carbon dioxide?
There are two such planets, Mars and Venus. Venus has a much thicker atmosphere than Mars, but both atmospheres are about 95% carbon dioxide.
Who's atmosphere is mostly CO2?
Both Mars and Venus have atmosphere made mostly of carbon dioxide. The atmosphere of Venus is much denser.
Which planet has a thick atmosphere which is mainly composed of carbon dioxide?
The atmosphere of Venus is the layer of gases surrounding Venus. It is composed primarily of carbon dioxide and is much denser and hotter than that of Earth.
What feature contributes strongly to the greenhouse effect on Venus?
the main reason is because of so much carbon dioxide co2.
How does the amount of carbon dioxide in the atmosphere affect the planets mars and Venus?
Mars has a thin atmosphere which does not make much difference. Venus has an atmosphere 93% carbon dioxide with a pressure of 95 Earth-atmospheres at the surface. Venus suffers global warming with surface temperatures over 400 degrees C.
Which planet hAs the thinnest atmosphere of mostly made of carbon dioxide?
Mars, Venus's atmosphere is thicker than Earth's. Much thicker.
What gas makes up most of the atmosphere of planet venus?
Venus is not made up of gas, but it does have a thick atmosphere. The main gas in the atmosphere is carbon dioxide, at about 96%. There's some nitrogen (about 3.5%) and traces of other things.
Do venus and earth have the same amount of carbon dioxide?
No, Venus has far more carbon dioxide. Earth's atmosphere is about .04% carbon dioxide. By contrast, Venus has an atmosphere that is 96% carbon dioxide and 93 times thicker than earth's. This means that Venus' atmosphere contains over 200,000 times more CO2 than earth's atmosphere does.
Why does venus have a stronger greenhouse effect than mars?
Venus has a stronger greenhouse effect than Earth because the atmosphere of Venus consists of about 96.5% carbon dioxide (CO2), which is the important greenhouse gas, and the atmosphere of Earth consists of about 0.04% CO2.
How much Sulfuric Acid is in Venus's?
The atmosphere of Venus has a high concentration of sulfuric acid vapor at and near the surface, but as you rise into the atmosphere, it's concentration drops sharply. The bulk of the cloud layers surrounding Venus are carbon dioxide.
How the presence of the carbon dioxide in Venus' atmosphere causes the average surface temp of Venus to be higher than the average surface temp on Mercury?
Carbon dioxide is what is colloquially known as a greenhouse gas. This means that while it is transparent to the incoming sunlight in the visible spectrum, it is opaque to the infrared frequencies by which a planet loses heat at night. So an atmosphere with carbon dioxide in it is like a warm blanket, wrapped around a planet, keeping in the heat. Earth has only about a third of one percent carbon dioxide in its atmosphere, so the greenhouse effect is not that strong. Venus, on the other hand, has a much higher concentration of carbon dioxide, and a much stronger greenhouse effect.
How do you describe Mars atmosphere?
The atmosphere of Mars is mostly carbon dioxide, rather like that of Venus, but much thinner.. It has smaller amounts of argon and nitrogen with trace amounts of methane.
