What else can I help you with?
Will the amount carbon dioxide the atmosphere soon be greater than the Amount of oxygen?
No, the amount of oxygen in the atmosphere is much greater than the amount of carbon dioxide. The current levels of carbon dioxide are approximately 0.04% of the atmosphere, while oxygen levels are around 21%.
What is the minimum amount of oxygen needed to sustain fire in the atmosphere?
The minimum amount of oxygen needed to sustain a fire in the atmosphere is about 16% oxygen. Below this level, the fire would not have enough oxygen to continue burning.
Why do scientist think the the amount of oxygen in the earth's atmosphere has increased?
Scientists believe that the amount of oxygen in Earth's atmosphere has increased over time due to the evolution of photosynthetic organisms, such as plants and cyanobacteria. These organisms release oxygen as a byproduct of photosynthesis, leading to an accumulation of oxygen in the atmosphere.
Which process increases the amount of oxygen and decreases the amount of carbon dioxide in the atmosphere?
Photosynthesis by green vegetation and forests.
Has the amount of oxygen released into the atmosphere increased in recent years?
The amount of oxygen released into the atmosphere has not noticeably increased in recent years. The amount of oxygen (O2) in the atmosphere is about 21%. It is part of the earth's oxygen cycle, the main driver of which is photosynthesis. Vegetation removes carbon dioxide (CO2) from the atmosphere, releases the oxygen (O2) and stores the carbon (C).
Earth's atmosphere is unique because it contains a significant amount of?
Oxygen! ^_^
How did earths atmosphere change during precambrian time?
During the Precambrian time, the Earth's atmosphere underwent significant changes, transitioning from a reducing atmosphere dominated by gases like methane and ammonia to an oxidizing atmosphere with increasing levels of oxygen, due to the development of photosynthetic organisms. This increase in oxygen levels laid the foundation for the evolution of complex multicellular life forms.
Do any of the planet have oxygen in their atmosphere?
Yes. There is one planet with oxygen in its atmosphere: our home planet Earth.
How the amount of oxygen in the atmosphere gradually increased?
The amount of oxygen in Earth's atmosphere increased gradually over millions of years due to the process of photosynthesis by early bacteria and later by plants. These organisms released oxygen as a byproduct, which accumulated in the atmosphere and changed its composition over time. This process, known as the Great Oxidation Event, occurred around 2.4 billion years ago and significantly increased the amount of oxygen in the atmosphere.
Is it true the greatest amount of gas in the air is oxygen?
No. If we look at the composition of gases in the atmosphere, the greatest amount of gas is nitrogen- 78%. Oxygen is 21% in the atmosphere. remaining 1% is carbon dioxide, carbon monoxide etc.
Why did the amount of oxygen's in earths atmosphere increase dramatically?
The amount of oxygen in the atmosphere increased because the number of photosynthetic organisms, which release oxygen, on the earth dramatically increased. This lead to the Great Oxygenation Event, or the Oxygen Crisis, 2.4 billion years ago - when this free O2 entered the Earth's atmosphere.
Which is the most accurate fraction for the amount of oxygen contained in earth's armosphere about 1 5 2 3 or 3 4?
The most accurate fraction for the amount of oxygen in Earth's atmosphere is about 1/5. Oxygen makes up about 21% of the Earth's atmosphere.
