If you are on a personal connection, like at home, you can run an anti-virus scan on your device to make sure it is not infected with malware. Log in. None of the planets in our solar system has a methane atmosphere, but Saturn's moon, Titan, has an atmosphere made of almost all methane. Uranus and Neptune have a lot of methane, but it is mostly frozen, not in the atmosphere. Titan, Saturn's moon, has a methane-rich atmosphere. They make up 10% of all 524 billion terrestrial planets 52‰ of all 820 billion planets in our galaxy. 1. Atmospheric methane concentrations are of interest because it is one of the most potent greenhouse gases in Earth's atmosphere. Those planets tend to be frigid, at around −290°F (−179°C). Methane planet is an assumed class of planet with surface covered in lakes or oceans of methane with methane clouds in the atmosphere like it is on Titan, the largest moon of Saturn. Edit : Also there is some methane on Uranus and Neptune. Credit: NASA > View streaming video > Larger, labeled image Mars today is a world of cold and lonely deserts, apparently without life of any kind, at least on the surface. The atmosphere of Uranus is composed primarily of hydrogen and helium.At depth it is significantly enriched in volatiles (dubbed "ices") such as water, ammonia and methane.The opposite is true for the upper atmosphere, which contains very few gases heavier than hydrogen and … PlanetStar Wiki is a FANDOM Lifestyle Community. None of the planets in our solar system has a methane atmosphere, but Saturn's moon, Titan, has an atmosphere made of almost all methane. Their atmospheres tend to be composed mostly of nitrogen (N2) and oxygen (O2) with variable amounts of methane (CH4) and trace amounts of nitric oxide (NO) and other gases. The 20-year global warming potential of methane is 84. However the weather activity on Neptune is much more active, and its atmosphere is much bluer than that of Uranus. Life on methane planets are strange that they can adapt to extreme cold and use methane as a solvent, whereas life on Earth use water as a solvent. Ask your question. But of course it is a moon not a planet. Methane planets tend to be hazy like Titan, because stellar radiation break methane molecules apart and form different hydrocarbons, such as ethane (C2H6), diacetylene (C4H2), methylacetylene (C3H4), acetylene (C2H2) and propane (C3H8). This image shows concentrations of Methane discovered on Mars. buttc349 buttc349 04/20/2020 Biology Middle School +5 pts. Biology. Methane planets tend to have similar climates to Earth's, except it uses methane as a "variable gas" instead of water vapor as it is on Earth. Its clouds are made of methane crystals and the planet is extremely cold. But Jupiter and Saturn have rocky cores. Under a hazy atmosphere, the plant life rely on chemosynthesis as there are not enough light for photosynthesis because methane planets orbit far from the light of their parent stars. It is about 80% hydrogen, 19% helium, and 1.5% methane. Completing the CAPTCHA proves you are a human and gives you temporary access to the web property. Viewed from space, methane planet would appear blue to aqua green because methane absorbs red light and reflects blue and green light. jupiter mars mercury or uranus Answers: 1 Get Other questions on the subject: Biology.

The main biogeochemical cycle on methane planet is the methane cycle compared to the carbon cycle here on Earth. Biology, 10.03.2020 05:28, DraeDrae138. Join now. That is, over a 20-year period, it traps 84 times more heat per mass unit than carbon dioxide (CO 2) and 32 … The life-bearing status on methane planets are fair. Answered Which of the following planets has methane clouds in the atmosphere? This breakdown can also produce non-hydrocarbons such as carbon dioxide (CO2), carbon monoxide (CO), hydrogen cyanide (HCN), cyanogen ((CN)2), and cyanoacetylene (C3HN). None of the planets in our solar system has a methane atmosphere, but Saturn's moon, Titan, has an atmosphere made of almost all methane.
