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.


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.


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.


What planets have carbon dioxide?

Venus and Mars are two planets in our solar system that have significant amounts of carbon dioxide in their atmospheres. Venus has a thick atmosphere composed mainly of carbon dioxide, while Mars has a much thinner atmosphere with trace amounts of carbon dioxide.


How are inner planets and atmosphere different?

Inner planets, also known as terrestrial planets, are composed primarily of rock and metal, and include Mercury, Venus, Earth, and Mars. They generally have thinner atmospheres compared to outer planets, with Earth being the exception due to its relatively dense atmosphere that supports life. The atmospheres of inner planets can vary significantly; for instance, Venus has a thick, toxic atmosphere, while Mars has a very thin one. In contrast, outer planets are gas giants with thick atmospheres composed mainly of hydrogen and helium.


Which rocky planets have well developed atmospheres?

Earth, Venus, and Mars have well-developed atmospheres compared to the other rocky planets in our solar system. Earth has a thick atmosphere that supports life, Venus has a thick and toxic atmosphere, while Mars has a thin atmosphere primarily composed of carbon dioxide.


Which Planets have atmosphere mostly carbon dioxide?

Venus and Mars haveatmospheres mostly consisting ofcarbon dioxide.


Do inner planets have atmospheres?

Yes, inner planets like Mercury, Venus, Earth, and Mars have atmospheres, although the composition and density of these atmospheres vary. For example, Venus has a thick and toxic atmosphere mainly composed of carbon dioxide, while Mars has a thin atmosphere primarily made up of carbon dioxide with traces of other gases. Earth has a diverse atmosphere with the right conditions to support life.


Which 2 inner planets have thick atmospheres?

Venus and Earth are the two inner planets with thick atmospheres. Venus has a thick atmosphere composed mainly of carbon dioxide, while Earth has a diverse atmosphere containing nitrogen, oxygen, and other trace gases.


Do the gas giants have thick or thin atmospheres?

Gas giants such as Jupiter and Saturn have thick atmospheres composed mainly of hydrogen and helium. These atmospheres can extend thousands of kilometers deep into the planets' interiors.


Which planets besides earth has an atmosphere?

All the other planets in our solar system have atmospheres, but their composition varies. For example, Venus has a thick atmosphere of carbon dioxide and sulfuric acid clouds, while Mars has a thin atmosphere primarily composed of carbon dioxide. Gas giants like Jupiter and Saturn have thick atmospheres mainly made up of hydrogen and helium.


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.
