What is giving the earth oxygen?
trees and plants also algae...trees take in carbon dioxide and release oxygen into the atmosphere .....so destroying trees effects the amount of oxygen in the air which then leads to global warming ....
What types of organisms remove oxygen from the atmosphere?
Animals remove oxygen from the atmosphere.
What percent of the Martian atmosphere is oxygen?
Mars' atmosphere contains 0.13% oxygen. Over 95% of the atmosphere on Mars is carbon dioxide.
Could you survive on Earth without the atmosphere?
No, because the atmosphere keeps in all the oxygen. Without the atmosphere the oxygen would escape.
What is todays current level of oxygen in air?
Oxygen levels in the atmosphere are steady at around 20%. The other main component of the air is nitrogen, with a small amount of other gases, including carbon dioxide (CO2).
What happened to ammonia and methane in earth's early atmosphere?
reacted out with oxygen as oxygen levels rose.
Oxygen levels first rose in the atmosphere because of?
volcanic outgasing
What effects does oxygen have on the earths atmosphere?
Without its oxygen content the Earth's atmosphere would be composed almost entirely of nitrogen and would be chemically inert; oxygen causes the atmosphere to be chemically active (and breathable by humans).
Describe oxygen cycle in nature?
Oxygen cycle is the movement of oxygen through the three reservoirs: the atmosphere, the biosphere and the lithosphere.
In an oxygen enriched atmosphere some possible sources of elevated oxygen levels include?
leaking oxygen cylinders and liquid oxygen systems in the immediate area
Respiration and photosynthesis keep the levels of carbon dioxide and oxygen in the atmosphere?
fairly constant
What type of scientist studies oxygen?
Chemists study oxygen, its chemical properties, and reactions involving oxygen Biologists study oxygen - it's availability and how it is used and produced by organisms Environmental scientists study how oxygen levels affect the environment and how the environment affects oxygen levels - including oxygen levels in both the atmosphere and dissolved in water.
How did the meteorite collision at the end of the Mesozoic affected the atmosphere and the biosphere?
The meteorite collision at the end of the Mesozoic era affected the atmosphere and biosphere by increasing the carbon dioxide levels and lowering oxygen levels.
Which of the following choices describes an oxygen deficient atmosphere?
An oxygen deficient atmosphere is one that lacks a sufficient amount of oxygen to support human or animal life. It can occur in environments where oxygen is depleted, such as in confined spaces or areas with high levels of carbon dioxide, gases, or chemicals that displace oxygen. Breathing in an oxygen deficient atmosphere can lead to suffocation or loss of consciousness.
Describe the significance of cyanobacteria in the formation of earth's atmosphere?
cyanobacteria also called blue-green algae is thought to be one of the first ever photosynthetic organism...prior to the evolution of photosynthetic organisms theoxygen percentage of the atmosphere was 0% and as we all know without oxygen (O2), ozone(O3) cannot form, and without ozone there can be no atmosphere. Photosynthetic organisms allowed for the formation of oxygen and brought oxygen levels to the percentage it is today (20% a significant increase from 0%) as a result ozone was able to form and ultimately the atmosphere emerged.
How did oxygen become a part of the earths atmosphere and what did this increase in oxygen levels allow?
The oxygen in the atmosphere is the O-Zone which is O3 (Oxygen 3) because of plant life oxygen had increased via photosynthesis, the incease just allowed the ozone to thicken, but sadly due to CFC there are large holes
Describe several ways gases enter and leave the atmosphere.?
plants take in carbon dioxide and release oxygen
