What Are The Atmospheric gases of each planet?

Answer 1

Mercury has a surface pressure that is near enough zero or a vacuum, since the planet holds no real atmosphere due to its small size and proximity to the sun.

The atmosphere on Venus is very thick, giving it a high surface pressure, some 93 times that of the Earths. Carbon Dioxide makes up around 96.5% of the atmosphere with around 3.5% Nitrogen. There are also small amounts of sulfur dioxide (0.0015), carbon monoxide (0.0017%), water vapour (0.002%), argon (0.007), helium (0.0012%) and Neon (0.0007%).

Earth has an atmosphere of 78.08% Nitrogen and 20.95% Oxygen, with 0.93% Argon and 0.038% Carbon Dioxide. Around 1% of the atmosphere is water vapour, with traces of other gases such as Neon, Xenon and Carbon Monoxide. Earths atmosphere is thicker than Mars', but not nearly as thick as Venus'.

Mars has a thin atmosphere, mainly of Carbon Dioxide (95.32%). Nitrogen makes up 2.7%, Argon 1.6%, Oxygen 0.13% and Carbon Monoxide makes up around 0.08%. There are other trace gases such as Water Vapour, Neon, Krypton, xenon, Molecular Hydrogen and Nitric Oxide. Mars' surface pressure is around 0.7 kPa, around 0.7% of Earths surface pressure.

Jupiter's atmosphere is mainly Hydrogen (around 90%), Helium (around 10%), with small amounts (minor gases) of Methane (around 0.3%), Ammonia (0.026%), Hydrogen Deuteride (0.003%), Ethane (0.0006%) and Water vapour (0.0004%).

Saturn's atmosphere is mainly Hydrogen (around 96%), Helium (around 3%), with small amounts of Methane, Ethane and Ammonia.

Uranus' atmosphere is mainly Hydrogen (around 83%), Helium (around 15%) and Methane (around 2.3%).

Neptune's atmosphere is mainly Hydrogen (around 80%), Helium (around 19%) and Methane (around 1%).

Answer 2

1. Mercury: thin atmosphere with trace amounts of oxygen, sodium, and hydrogen.
2. Venus: thick atmosphere mainly composed of carbon dioxide, with traces of nitrogen and sulfuric acid clouds.
3. Earth: nitrogen (78%), oxygen (21%), with traces of argon, carbon dioxide, and other gases.
4. Mars: carbon dioxide (95%), nitrogen (3%), argon (1.6%), with traces of oxygen and water vapor.
5. Jupiter: mainly hydrogen (75%) and helium (24%), with traces of methane, ammonia, and water vapor.
6. Saturn: primarily hydrogen (96%) and helium (3%), with traces of methane and ammonia.
7. Uranus: predominantly hydrogen (82%) and helium (15%), with traces of methane.
8. Neptune: similar to Uranus with hydrogen (80%), helium (19%), and methane (1.5%).
