Where do birds fly in the atmosphere?
Because bacterial life can survive in the stratosphere, this layer of the atmosphere belongs to the biosphere. Some species of birds have even been reported to fly in the lower levels of the stratosphere.
How much gas is in the atmosphere?
The air in Earth’s atmosphere is made up of approximately 78 percent nitrogen and 21 percent oxygen. Air also has small amounts of lots of other gases, too, such as carbon dioxide, neon, and hydrogen.
Why nitrogen gas is more in atmosphere?
Nitrogen is not stable as a part of a crystal lattice, so it is not incorporated into the solid Earth. This is one reason why nitrogen is so enriched in the atmosphere relative to oxygen. Thus, over geological time, it has built up in the atmosphere to a much greater extent than oxygen.
What is atmosphere question and answer?
Atmosphere is the thin layer of air that surrounds the earth. It is made up of various gases such as oxygen, nitrogen, carbon dioxides, dust particles and water vapour. The gravitational force of the earth holds the atmosphere around it. It protects us from harmful rays and scorching heat of the sun.
What are the four most abundant gases in the atmosphere?
Usually, the 4 most abundant gases are:
- Nitrogen (N2) – 78.084%
- Oxygen (O2) – 20.9476%
- Argon (Ar) – 0.934%
- Carbon dioxide (CO2) 0.0314%
How does air exist?
So in conclusion, we know air exists because first of all, we breathe it everyday and its necessary for most things living on this earth. You can prove air exists by blowing up a balloon. By doing this, it proves that air has weight and air takes up space. Lastly, air is just made up of mainly nitrogen and oxygen.
What is the most abundant gas in the atmosphere?
nitrogen
What layer of atmosphere do planes fly in?
stratosphere
How was the atmosphere created?
When Earth formed 4.6 billion years ago from a hot mix of gases and solids, it had almost no atmosphere. The surface was molten. As Earth cooled, an atmosphere formed mainly from gases spewed from volcanoes. It included hydrogen sulfide, methane, and ten to 200 times as much carbon dioxide as today’s atmosphere.

What are the importance of the atmosphere?
The atmosphere protects living things from the Sun’s most harmful rays. Gases reflect or absorb the strongest rays of sunlight (figure below). The atmosphere shields Earth from the most harmful solar rays.
What are the disadvantages of atmosphere?
Drawbacks
- The atmosphere holds in some “greenhouse” gases that retain the heat of the Sun.
- Clouds regularly obscure good astronomical viewing.
- The atmosphere refracts light which means the position and clarity of star viewing is less accurate.
- Pollution from light and chemicals obscure observations.
What are main components of air?
The air in the atmosphere consists of nitrogen, oxygen, which is the life-sustaining substance for animals and humans, carbon dioxide, water vapour and small amounts of other elements (argon, neon, etc.). Higher in the atmosphere air also contains ozone, helium and hydrogen.
What separates the atmosphere from space?
Exosphere
What are the 5 gases in the atmosphere?
According to NASA, the gases in Earth’s atmosphere include:
- Nitrogen — 78 percent.
- Oxygen — 21 percent.
- Argon — 0.93 percent.
- Carbon dioxide — 0.04 percent.
- Trace amounts of neon, helium, methane, krypton and hydrogen, as well as water vapor.
