What gases are in air?
78% Nitrogen, 21% Oxygen, 1% trace gases
What is air made up of?
air is made up of some gases. i.e. it's made up of hydrogen, nitrogen, and mixture of other gases. but the most common is it is made up of nitrogen-78%, oxygen-21%, and other gases-1%air is made up of different gases such as oxygen, carbondioxide, nitrogen and noble gases.
What are two the most common gasses found in air and what are their percentages?
Gases in air are nitrogen about 79%, oxygen about 20% and other gases 1%
What is the term for a person with assets over 1000 million dollars?
billion air
How are gases used in real life?
in burning things, to breath in air etc.
How would such air be similar from 3.6 billion years ago than the air you breathe today?
it would still be smoggy
How would such air be different from 3.6 billion years ago than the air you breathe today?
The air 3.6 billion years ago would have contained very little oxygen, mostly consisting of carbon dioxide, nitrogen, and water vapor. Today, Earth's atmosphere has significantly more oxygen due to the process of photosynthesis by plants and cyanobacteria. Additionally, the presence of pollutants and greenhouse gases in the air today is much higher compared to that ancient time.
Which gas was not present on earth at its formation 4.6 billion years ago out of methane water vapour oxygen and nitrogen?
Oxygen was not present on Earth 4.6 billion years ago when it was initially formed. The early atmosphere consisted mostly of methane, water vapor, nitrogen, and carbon dioxide. Oxygen levels increased later due to processes like photosynthesis.
What was not in the air on earth 3.6 billion years ago?
Oxygen was not present in the Earth's atmosphere 3.6 billion years ago. The atmosphere at that time was primarily composed of carbon dioxide, nitrogen, methane, and water vapor. Oxygen began to accumulate in the atmosphere around 2.5 billion years ago as a result of photosynthetic organisms.
How did earth come to have an oxygen rich atmosphere?
Algae activity
What was in the air 1 million years ago?
The air 1 million years ago was pretty much the same as it is now.
What is the oldest form of air pollution?
Oxygen, produced by the first blue-algae about 3 billion years ago. It poisoned much of the other kinds of life around at the time.
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.
Was there carbon dioxide in the air when the earth was young?
In the very young earth the atmos. was mostly carbon dioxide. This caused the earth to have a very warm atmosphere. There was no life at that time on earth. It was a few billion years ago.
Did Earth form 4.6 billion years ago?
Current Scientific Theories indicate that the Earth was formed 4.6 billion years ago by the various rocks and other materials that expanded after the Big Bang, and likely other Cosmic Materials that contributed to the formation of other planets. Asteroids were common, and each time they hit what would be the Earth, the cycle of "cooling down" the crust was interrupted, but the total mass of the Earth would grow. [Think of it like mashing two pieces of clay together and rolling them into a ball, and how the ball consistently grows every time in size] Until eventually the activity likely settled, or the period was long enough without large asteroids or collisions with large planetary bodies. Comets and general weathering and presentation of chemicals into the environment produced the gases of the atmosphere, plant life logically forming first and transforming CO2 into Air, thus allowing for the evolution of life from sea-based to land-based. More formations, as well as the theory of plate tectonics, would give the earth its current shape.
What flying transport did people use years ago?
Air planes
How many years is it since the munich air crash?
It happened in 1958 - 54 years ago.
