How much oxygen is in the air in 1973?
In 1973, the composition of Earth's atmosphere was roughly the same as it is today, with oxygen making up about 21% of the air.
Does composition of the atmosphere change with elevation?
The atmosphere gos through many cycles and changes. The significant gases in our atmosphere have not changed substantially in the past several centuries. The primary gas is still Nitrogen, then Oxygen.
How does the composition of air change at the top of amountain?
The composition is the same, the air is just less dense.
Why is the amount of gases in the atmosphere usually shown as percentages of dry air?
Showing the amount of gases in the atmosphere as percentages of dry air allows for easy comparison and analysis of the composition of the atmosphere. Since the composition of dry air is relatively stable, expressing the gases as percentages of dry air helps to standardize the data for scientific purposes.
Why does lightining change color?
Lightning changes color because of different gases and particles in the atmosphere that affect the way light is scattered. The color of lightning can be influenced by the distance it travels through the atmosphere, the composition of the gases in the atmosphere, and the temperature and density of the air.
Is air the same as atmosphere yes or no?
no
Why air is not a heterogeneous mixture?
Well, air contains 78.09% of Nitrogen, 20.95% of Oxygen, 0.03% of Carbon Dioxide and the rest of the gases like Argon, Helium, etc for about 1%. This composition of air is the same no matter where you go. If you're in Australia, the air will have this composition. If you're in South Africa, the air will have the same composition. The basic idea here is that the composition of air doesn't change which means air has a uniform composition. Homogeneous mixtures are those mixtures whose composition is same throughout the mixture and a heterogeneous mixtures are those mixtures whose composition is not same. Also, homogeneous mixtures are mixtures in which its components mix up thoroughly, i.e., the components cannot be observed whereas in a heterogeneous mixture, the individual components can be observed. In air, the Nitrogen or Oxygen cannot be observed separately. It is uniform and homogeneous. Thus, air is not a heterogeneous mixture.
What is the role of argon in air and how does it affect the composition of the atmosphere?
Argon is a noble gas found in the Earth's atmosphere. It makes up about 0.93 of the air we breathe. Argon is chemically inert, meaning it does not react with other elements. Its presence in the atmosphere helps maintain the overall composition and stability of the air. Argon does not play a significant role in the chemical reactions that occur in the atmosphere, but its presence is important for maintaining the balance of gases in the air.
How does the atmosphere composition today compare with the air 1000 years ago?
The composition of the atmosphere today is different compared to 1000 years ago due to human activities. The increase in greenhouse gases such as carbon dioxide has led to global warming and climate change. This change in composition is impacting the Earth's climate and ecosystem.
Is the atmosphere always the same explain why or why not?
No, the atmosphere is not always the same. It can vary in composition and characteristics due to factors like weather patterns, human activities, and natural events like volcanic eruptions. These variations can impact things like air quality, temperature, and precipitation patterns.
Does the atmosphere always stay the same?
No, the atmosphere is constantly changing due to processes like evaporation, condensation, and air movement. Factors like weather patterns, human activities, and natural events can also influence the composition and behavior of the atmosphere.
Why Is air a homogeneous mixture and not a compound?
The composition of air is practically the same at the level of earth.
