Venus and Mars both have atmospheres composed of about 95% carbon dioxide.
Mars's atmosphere is very thin, with a pressure of 0.7 kilopascals, compared to the Earth's 1013 kilopascals.
Venus's atmosphere has a pressure at the surface of about 94,000 kilopascals, about 0.6 tons per square inch.

How does the chemical composition of the terrestrial planet atmospheres differ from the Jovian planets?
Terrestrial planet atmospheres are primarily composed of gases like nitrogen and oxygen, with small amounts of carbon dioxide and other trace gases, while Jovian planet atmospheres consist mostly of hydrogen and helium, along with traces of methane and ammonia. Terrestrial planets have thinner atmospheres compared to Jovian planets, which have massive, thick atmospheres made up of mostly hydrogen and helium.
Which two planets have atmospheres composed mostly carbon dioxide include?
Mars and Venus
What are the atmospheres of the outer planets like?
Outer planets like Jupiter and Saturn have thick atmospheres composed mostly of hydrogen and helium. Uranus and Neptune have atmospheres rich in frozen ices like water, ammonia, and methane. Strong winds, massive storms, and unique cloud formations characterize the atmospheres of these outer planets.
Which planets have atmospheres?
All planets in our solar system have atmospheres, but their compositions and characteristics vary. For example, Venus has a thick and toxic atmosphere primarily composed of carbon dioxide, while Mars has a thin atmosphere mainly made up of carbon dioxide. Earth's atmosphere is mostly nitrogen and oxygen. Gas giants like Jupiter and Saturn have thick atmospheres composed mostly of hydrogen and helium.
Which planets are mostly made of and atmosphere?
The gas giants Jupiter and Saturn are primarily composed of hydrogen and helium, with thick atmospheres surrounding their dense cores. Uranus and Neptune, the ice giants, have atmospheres rich in methane, ammonia, and water, along with a mixture of hydrogen and helium. These planets have minimal solid surfaces compared to terrestrial planets, making their atmospheres a significant part of their overall structure.
What are the giant planets mostly made of?
The giant planets in our solar system, such as Jupiter and Saturn, are mostly made of hydrogen and helium, with smaller amounts of other elements like methane, ammonia, and water. These planets have thick atmospheres and lack a solid surface.
What are the two major ways that the terrestrial planets and the jovian planets differ?
Terrestrial planets are small, rocky, and have solid surfaces, while jovian planets are large, gaseous, and lack solid surfaces. Jovian planets also have thick atmospheres composed mostly of hydrogen and helium, while terrestrial planets have thinner atmospheres with varying compositions.
Do other planets not including earth have atmospheres?
Yes, other planets in our solar system have atmospheres. For example, Venus has a thick, toxic atmosphere primarily composed of carbon dioxide, while Mars has a much thinner atmosphere composed mostly of carbon dioxide. Gas giants like Jupiter and Saturn also have thick atmospheres made up of hydrogen and helium.
How do Jovian and terrestrial planets compare?
Jovian planets are gas giants made mostly of hydrogen and helium, while terrestrial planets are rocky planets with solid surfaces. Jovian planets are much larger in size and have thick atmospheres, while terrestrial planets are smaller and have thinner atmospheres. Jovian planets have many moons and ring systems, while terrestrial planets have fewer moons and no rings.
Is the four gas giants planets mostly rocks?
No, the four gas giants (Jupiter, Saturn, Uranus, Neptune) are primarily composed of hydrogen and helium gases with small rocky cores. These planets have thick atmospheres that are mainly hydrogen and helium with trace amounts of other elements.
How come out of all of the planets earth has earth has gravity and air?
All of the planets of gravity and all except for Mercury have atmospheres. All of the planets have enough mass to produce noticeable gravity, but the strength of that gravity varies depending on their mass and diameter. The atmospheres of the planets vary in composition and might not exactly be considered air. Venus and Mars have atmospheres made mostly of carbon dioxide, which likely originated from volcanoes. Jupiter, Saturn, Uranus, and Neptune have atmospheres made mostly of hydrogen and helium, which were present in great abundance when the solar system was forming. Earth probably had a mostly carbon dioxide atmosphere in its early history, but plants an algae removed most of the carbon dioxide and replaced it with oxygen, leaving behind the nitrogen to produce the atmosphere we have now. Mercury does not have an atmosphere because its relatively weak gravity and close proximity to the hot sun do not allow it to hold on to one.
What is a gas planet made out of?
Gas planets, such as Jupiter and Saturn, are primarily composed of hydrogen and helium, with smaller amounts of other gases like methane and ammonia. These planets lack a solid surface and instead have thick atmospheres that extend many thousands of kilometers into space.
