Jupiter: 90% hydrogen 10% helium 0.3% methane Saturn: 90% hydrogen 3.5% helium .5% methane Uranus: 83% hydrogen 15% helium 2% methane Neptune: 80% hydrogen 19% helium 2% methane

which planets have the most similar atmospheres
i think its Uranus and Neptune am i correct?

Yes, you are correct. Uranus and Neptune have the most similar atmospheres among the given planets. Both have a higher percentage of methane compared to Jupiter and Saturn. Furthermore, the ratios of hydrogen and helium in their atmospheres are closer to each other as well.

Yes, you are correct. Uranus and Neptune have the most similar atmospheres among the given options. Both Uranus and Neptune have a higher percentage of hydrogen and helium compared to methane. Additionally, they have a higher percentage of methane compared to Jupiter and Saturn. Overall, Uranus and Neptune have similar compositions in terms of hydrogen, helium, and methane.

Yes, you are correct! Uranus and Neptune have the most similar atmospheres among the provided options.

To determine this, you need to compare the percentages of the different gases present in the atmospheres of these planets. Here's a breakdown of the gas compositions:

Jupiter: 90% hydrogen, 10% helium, 0.3% methane
Saturn: 90% hydrogen, 3.5% helium, 0.5% methane
Uranus: 83% hydrogen, 15% helium, 2% methane
Neptune: 80% hydrogen, 19% helium, 2% methane

By comparing the percentages, you can see that Uranus and Neptune have similar proportions of hydrogen, helium, and methane. Both Uranus and Neptune have higher percentages of methane compared to Jupiter and Saturn. Therefore, Uranus and Neptune indeed have the most similar compositions of their atmospheres.
