Does Io have a solid surface?
Jupiter’s fifth moon, Io, is the most volcanically active body in the solar system. Plumes of sulfur spew upward as high as 190 miles (300 kilometers). The surface of Io is splotched with lava lakes and floodplains of liquid rock.
What is the surface of Io like?
The surface of Io is completely volcanic, with lava flows of sulfur from the interior, as shown in this image. White patches in the image are areas of frost made of sulfur dioxide instead of water. Io is a small moon, very close to Jupiter, and well inside the other 3 main moons.
Why is Io so cold?
When Io passes into Jupiter’s shadow, and is out of direct sunlight, it is too cold for sulfur dioxide gas, and it condenses onto Io’s surface. During that time, we can only see volcanically-sourced sulfur dioxide. We can, therefore, see exactly how much of the atmosphere is impacted by volcanic activity.
What is the only moon that has a thick atmosphere?
Titan
Our solar system is home to more than 150 moons, but Titan is unique in being the only moon with a thick atmosphere.
How long is a day on Io?
The atmosphere is collapsed and trapped as surface ice for about two hours each day on Io (note: A day on Io is equal to 1.7 Earth days, because that’s how long it takes the body to rotate on its axis in relation to the sun. An “hour” is the same on any planet, because it’s an arbitrary, purely human measure of time).
Can we live on Io?
This means Io is a land of both fire and ice. Io is generally considered a poor candidate for life because of all the radiation Jupiter blasts it with. In addition, no organic molecules have been detected on its surface, and it has only an extremely thin atmosphere devoid of detectable water vapor.
What is the force of gravity on Io?
1.796 m/s²
Io/Gravity
Is there life on Io?
Io is generally considered a poor candidate for life because of all the radiation Jupiter blasts it with. In addition, no organic molecules have been detected on its surface, and it has only an extremely thin atmosphere devoid of detectable water vapor.
What is the most abundant gas in Titan’s atmosphere?
nitrogen
98.4% is nitrogen. in Titan’s atmosphere.
What causes Io’s surface to bulge up and down?
Thus, in its widely varying distances from Jupiter, Io is subjected to tremendous tidal forces. These forces cause Io’s surface to bulge up and down (or in and out) by as much as 330 feet (100 meters). Compare these tides on Io’s solid surface to the tides on Earth’s oceans.
How does Io’s orbit affect its volcanic activity?
Io’s rock surface bulges up and down by as much as 100 meters (328 feet) during the process. This affects Io’s volcanic activity in a similar way to which Earth’s oceans react to the moon. Io’s irregularly elliptical orbit also heightens the tidal activity.
How does corrosion take place in a stationary condition?
N. Le Bozec, in Encyclopedia of Interfacial Chemistry, 2018 Atmospheric corrosion seldom takes place under stationary conditions with constant humidity and temperature. Instead, metal surfaces are exposed in the atmosphere subjected to periodic wetting and drying events as well as periodic variations in humidity and temperature.
Which is the stationary condition of the functional?
The stationary condition of the functional (6.45) is given, by partial differentiation with respect to Ri ( i = 0 – N) as (6.46) 0 = − 1 2 ∂ I ∂ Ri = − ∫D 0 dR dρ dϕ dρρdρ + υ 2∫D 0q(ρ)Rϕ iρdρ − w 2∫D 0Rϕ iρdρ − wDK1 ( wD) K0 ( wD) R Nδ i, N (i = 0 − N).
