What else can I help you with?
What is the oxygen content of the atmosphere?
The atmosphere is 79.9% oxygen.
What is the proportion of oxygen in the atmosphere today?
About 21% of the Earth's atmosphere is oxygen.
What atmosphere we live on?
The main components of Earth's atmosphere are nitrogen and oxygen. Of these, oxygen is the one we can't live without.
Does the atmosphere get thicker the higher you go?
No, the atmosphere does not get thicker as you go higher; it actually becomes thinner. As altitude increases, the air pressure decreases, leading to a lower concentration of air molecules. This means that at higher elevations, the atmosphere is less dense, resulting in less oxygen and lower overall air pressure.
Where did oxygen in the atmosphere came from?
Oxygen in the atmosphere primarily comes from photosynthesis by plants and other photosynthetic organisms. These organisms use sunlight to convert carbon dioxide into oxygen as a byproduct. Over millions of years, this process has led to the accumulation of oxygen in the Earth's atmosphere.
Which process increases the amount of oxygen and decreases the amount of carbon dioxide in the atmosphere?
Photosynthesis by green vegetation and forests.
Where in atmosphere does meteoroids burn?
"where the oxygen level increases then combustion takes place"
What processes increase carbon dioxide and oxygen in the atmosphere?
Processes that increase carbon dioxide in the atmosphere include burning fossil fuels, deforestation, and industrial activities. Photosynthesis by plants and algae is a key process that increases oxygen in the atmosphere.
How does the light reaction of photosynthesis affect the earths supply of oxygen?
Photosynthesis is the source of virtually all the free oxygen in the earth's atmosphere.
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.
As elevation increases this becomes thinner?
The atmosphere. As you go higher in elevation, the atmosphere becomes thinner because the air pressure decreases, leading to lower air density.
What is the oxygen content of the atmosphere?
The atmosphere is 79.9% oxygen.
What percent of the atmosphere is oxygen'?
21% of the atmosphere is oxygen.
What is the process in which oxygen increases and carbon dioxide decreases in plants?
The process in which oxygen increases and carbon dioxide decreases in plants is called photosynthesis. During photosynthesis, plants absorb carbon dioxide from the atmosphere and water from the soil, using sunlight as energy to convert these into glucose and oxygen. The oxygen is released as a byproduct into the atmosphere, while the glucose is utilized for energy and growth. This process not only sustains the plant itself but also contributes to maintaining atmospheric balance.
What is the percent of oxygen that would make us flammable?
The atmosphere becomes highly flammable when the concentration of oxygen reaches about 23.5%. Above this level, the risk of fires and explosions increases significantly.
What is an aerobic atmosphere?
the environment which has the availability of oxygen it is called aerobic atmosphere and if the availability of oxygen is not there in atmosphere then it is anaerobic type We live in a aerobic atmosphere which has the oxygen available
What happens to oxygen as the distance from the surface increases?
As the distance from the surface increases, the concentration of oxygen in the atmosphere decreases due to lower air pressure. This decrease in oxygen availability can make it harder for living organisms to breathe at higher altitudes.
