What else can I help you with?
Is oxygen found more in the earth's atmosphere more than argon?
Yes, the earths atmosphere has around 20% oxygen, but less than 1% argon.
What process provides most of the oxygen found in earths atmosphere?
Growing more trees as trees take in carbon dioxide and releases oxygen that we use for breathing. So. I guess Afforestation provides most of the oxygen found in the earths atmosphere.
As life began to populate earths surface what change was seen in the atmosphere?
more oxygen was consumed
Why earths atmosphere today contains more oxygen than earth atmosphere?
The increased oxygen levels in Earth's atmosphere today compared to earlier in its history are due to the evolution and proliferation of photosynthetic organisms like plants and cyanobacteria. These organisms release oxygen as a byproduct of photosynthesis, gradually increasing its concentration in the atmosphere over millions of years.
Why does earths atmosphere today contain more oxygen then the early earth?
The increase in oxygen in Earth's atmosphere is mainly due to the evolution of photosynthetic organisms like cyanobacteria and plants, which produce oxygen as a byproduct. Over time, these organisms gradually increased oxygen levels through the process of photosynthesis. This led to the rise of oxygen in the atmosphere from less than 1% to the current level of around 21%.
What element is not found in large quantities in Earths mantle?
The element carbon is not found in large quantities in Earths mantle.
What effect does photosynthesis have on the amount of oxygen in the atmosphere?
Photosynthesis is the source of virtually all the free oxygen in the earth's atmosphere.
What gives more oxygen to the atmosphere?
Plankton gives more oxygen to the atmosphere.
Which organisms do scientists estimate more than 50 percent of the oxygen in earths atmosphere?
Scientists estimate that more than 50 percent of the oxygen in Earth's atmosphere is produced by phytoplankton in the ocean through photosynthesis. Phytoplankton are microscopic marine organisms that play a crucial role in the global oxygen cycle.
Does the atmosphere have more nitrogen or oxygen in it?
The atmosphere contains more nitrogen than oxygen. Approximately 78% of the atmosphere is nitrogen, while oxygen makes up about 21%. The remaining 1% consists of other gases like argon, carbon dioxide, and trace gases.
How does the composition gases changes as you travel in earths atmosphere?
As you travel higher in Earth's atmosphere, the composition of gases changes in terms of their concentration. Oxygen, nitrogen, and argon are the most abundant gases in the lower atmosphere, while the percentage of oxygen decreases and other gases like helium and hydrogen become more prevalent in the upper atmosphere. The overall pressure also decreases with altitude, causing the air to become less dense.
What effect do photosynthetic marine plankton have on the composition of the atmosphere?
Marine plants contribute far more oxygen to the earths atmosphere than land plants they also use up a lot of CO2 in so doing.
