Other planets do have oxygen, but not in as high of concentration as we have here on Earth.
Earth is the only known planet with an oxygenated atmosphere.
So far the answer is Earth... But we are still looking around...
The oxygen in Earth's atmosphere comes from photosynthesis, which is carried out by plants and algae. Earth is the only planet known to have life, which is the only way we know of that would cause a planet to have an oxygen-rich atmosphere. Oxygen can form from the chemical breakdown of water via sunlight, but only in trace amounts.
There is no oxygen on the moon, which is what makes earth unique. We are the only planet that we know of in the universe with oxygen
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)
beause earth is the only planet which has oxygen and other needed sudstances .
Our planet, the Earth is the only planet with drinkable water. It is the only planet in our Solar System with life and oxygen. Without the oxygen, there will be no life and water on Earth.
Earth is the only known planet with an oxygenated atmosphere.
only earth idiot
Earth is the only planet known to have a significant amount of oxygen molecules in its atmosphere.
Because it is the only planet that have oxygen and have water and food on it.
earth is supposedly the only planet that can sustain life and has oxygen
So far the answer is Earth... But we are still looking around...
The Earth(our planet(home sweet home)) is the planet with wildlife. It is the only planet with wildlife because there is oxygen on Earth but not others, in fact.
Earths atmosphere is rich in Oxygen, some 21% of the air is Oxygen. There is oxygen on other planets, but the percentage comes nowhere close to this. The percentage of Oxygen in earths atmosphere is thought to have been much higher in the past, before animals were about, but after the arrival of plants.
Earth is the only known planet to have significant amounts of free oxygen in its atmosphere. Also, it's the only planet in our solar system where nitrogen is the main gas in the atmosphere.
Earth is only one planet where gaseous oxygen is found. The Earth's atmosphere is about 21% Oxygen.
