Why is oxygen such an important part of th Earth's atmosphere?
Oxygen is important because us humans have to breath and our brain have to function.
5 What has Earths atmosphere got that no other planet has that enables us to live?
Earth's atmosphere contain significant amounts of oxygen, no other planet in the solar system has it - it may well be that other planets in the galaxy do have oxygen. It's not just oxygen though; if the atmosphere was pure oxygen it would kill us very quickly. It's the combination of gases; oxygen, nitrogen, hydrogen, etc, etc know as AIR, together with its pressure of around 15 psi that enables us to live here on earth.
Can you make air on Mars?
That depends on what the bubble is made out of. If you are talking about a soap bubble, no. There is only a virtual atmosphere on Mars - just a bit of this and that floating around. The pressure of just about any amount of gas applied to blow a soap bubble would burst it immediately. The soap film is only strong enough to make a bubble in a situation where there is some amount of atmosphere around it. On Earth, we have the pressure of the atmosphere all around us under normal circumstances. On Mars, forget it. Of course, if you constructed a pressure dome there, you could maintain the same sort of atmospheric pressure that exists naturally on Earth.
Can you live without the sun or moon?
No. It would be impossible. The moon doesn't matter that much but the sun does. The sun is what keeps plants alive which gives us oxygen. The sun also gives us warmth and keeps us from freezing to death. I hope this helps. Give me a trust point please if it does!
Is the atmosphere mostly composed of oxegyn gas?
No, our atmosphere is composed mainly of nitrogen (78%). Oxygen comprises around 21% of the atmosphere. Water vapor makes up 1.247% of the atmosphere, the rest being made up of Argon, Carbon dioxide, and trace gases. (The Carbon dioxide protects us from being fried by certain particles flowing from the Sun)
What is significance of air?
Our atmosphere protects us from harmful radiation and also gives us the oxygen we need to breathe.
Where the animals get the oxygen they need?
Land animals get the oxygen they need from the atmosphere. Most aquatic organisms get oxygen dissolved in the water in which they live, and others, like alligators and crocodiles, get oxygen from the atmosphere. Most Plants Give Out Oxygen, And Plants Are All Around Us.
Is most of earth' s atmosphere oxygen?
Most of the oxygen is in the troposphere. Stratosphere contains ozone. It is the converted oxygen.
Which gas in earth's atmosphere tells us that there is life on earth?
Oxygen, Nitrogen and Carbon dioxide, in that order. The most important element to sustaining life is Oxygen.
What is the three most important things that plant gives us?
sun oxygen and life
How does the atmosphere preserve life on Earth?
There is oxygen in the atmosphere. This lets us breathe.
What part of the atmosphere gives us protection?
The ozone layer gives us the protection from radiation
What percentage of the air around us is oxygen?
The percentage of oxygen in the atmosphere is 20.75%. The atmosphere has many other elements that we breathe in besides oxygen. Oxygen needs to be present for life on earth.
Why is the earth the most suitable planet for us to live on?
We have the most water, and we have a adequate atmosphere that hold oxygen and carbon dioxide for living things to breathe in.
Does grass gives us oxygen?
Yes
What element gives us life?
oxygen
Would the atmosphere of Earth protect us from a meteorite?
no, it is not strong enough to hold back a meteorite. It protects us from the suns deadly rays though. The atmosphere also gives us oxygen to breath, but if a meteorite the size of the earth came crashing down on us, then we would all be dead and the Earth would be destroyed.
