What is free atmosphere?
The free atmosphere refers to the layer of the Earth's atmosphere above the planetary boundary layer where air moves freely and is not influenced by the Earth's surface. It is typically above the lowest few kilometers of the atmosphere and is important for understanding atmospheric processes on a larger scale.
What is the highest part of the earths atmosphere?
The highest part of the earths atmosphere is called the Exosphere. The main gases within the Earth's exosphere are the lightest gases, mainly hydrogen, with some helium, carbon dioxide, and atomic oxygen near the exobase. The exosphere is the last layer before outer space. Since there is no clear boundary between outer space and the exosphere, the exosphere is sometimes considered a part of outer space.
Is oxygen part of the atmosphere?
Yes, molecular oxygen makes up about 20% of the atmosphere at sea level.
Is the moon part of earths atmosphere?
Yes and no. Our atmosphere is part of the earth, and when you see the blue sky you are actually seeing the light scattered by the atmosphere. Of course if you think of the sky as going all the way to the distant stars, then you are no longer talking about the earth's atmosphere.
What part of body directly accepts oxygen from atmosphere?
The lungs are responsible for directly accepting oxygen from the atmosphere during the process of breathing. Oxygen is taken in through the lungs' alveoli, which are tiny air sacs where gas exchange occurs, allowing oxygen to enter the bloodstream and carbon dioxide to be released.
What gas was not part of early earths atmosphere?
oxygen
Where is oxygen obtained for mammals?
Obtained by Earths atmosphere which is 20% Oxygen and processed by the aveoli (part of the lung).
Why is oxygen such an important part of the earth's atmosphere?
Oxygen is necessary for most organisms to carry out their life functions.
Is the sea part of the earths atmosphere?
No. It is part of the hydrosphere.
What important gas is part of earth s atmosphere?
I'd say the most important gasses in the Earth's atmosphere are oxygen and water vapour.
What gas became part of Earths atmosphere mainly as a result of the evolution of life-forms?
Oxygen became part of Earth's atmosphere mainly as a result of the evolution of life forms, particularly through photosynthesis by early cyanobacteria and plants. This process involved converting carbon dioxide into oxygen as a byproduct, leading to the oxygen-rich atmosphere we have today.
Why is the atmosphere classed as an oxygen atmosphere?
Earth's atmosphere is mainly nitrogen, oxygen, carbon dioxide, and water vapor. Oxygen is the most reactive of these. Oxygen allows all of the life as we know it on earth. Even though oxygen is less than 1/4 of the atmosphere it is the most important part.
What gas was not a part of earths early atmosphere?
nitrogen
What is a gas upper part of of earths atmosphere?
ozone
Where is most of the water vapor and carbon dioxide in earths atmosphere found?
Upper Part
What part of earths spheres is composed of a mixture of gases?
the entire atmosphere...
Is hydrogen part of earths atmosphere?
Yes. Hydrogen is part - albeit a very small part - of the Earth's atmosphere. Typically it makes up about 0.000055% of the atmosphere
