Yes Oxygen is present in other planets.
Earth has an ozone layer in atmosphere. It is present in the stratospheric region. Other planets which have oxygen in their environment might have ozone.Some planets like earth do. Others might have.
This is because there is absolutely no trees on other planets.Mean while the trees are the propagators of oxygen on earth.hence the absence of oxygen on other planets.
because you need biological life. You also need liquid water. Mars does have oxygen @ very low levels. Other planets do have oxygen.
No, there is no oxygen on any other planet other than Earth because there is no planet life on the other planets.
Probably. Small amounts of oxygen has already been detected on other planets (and moons) within our solar system, including:Saturn's moon RheaJupiter's moons Europa and GanymedeMars (0.13% of the atmosphere)
No. Only Earth has a significant amount of oxygen. (I guess you mean oxygen as the gaseous element. Oxygen does occur on other planets in compounds like carbon dioxide.)
Yes, traces of oxygen have been detected on other planets in our solar system. For example, Mars has a very thin atmosphere with small amounts of oxygen, mostly in the form of carbon dioxide. Additionally, there is evidence of oxygen on planets outside our solar system through observations made by telescopes.
Yes. Most of the planets in our solar system and presumably most of the extrasolar planets too have a range of amounts of oxygen present. However, only on a very few of them is it in elemental form; on the others it is combined with other elements such as on Venus in the form of carbon dioxide and on Mars in the form of iron oxides. So far only Earth is known to have significant amounts of oxygen in its atmosphere.
Because it could be sign of life.
Within our solar system at the present time, no. Regarding planets orbiting other stars outside our solar system, our present technology is nowhere near able to tell.
because no oxygen on other planet
Earth is the only planet known to have a significant amount of oxygen molecules in its atmosphere.
