Air is the mixture of gases that surrounds the Earth. The composition of the earth's atmosphere varies with altitude, but at sea level contains approximately 78% nitrogen and 21% oxygen by volume.An oxygen-deficient atmosphere contains less than 19.5% oxygen by volume.An oxygen-enriched atmosphere contains more than 23.5% oxygen by volume.
Yes, a monitoring device that is labeled as intrinsically safe and explosion-proof can be used in an oxygen-enriched atmosphere. These safety ratings ensure that the device will not ignite or cause a spark that could lead to an explosion, even in an environment with heightened oxygen levels.
Autotrophic prokaryotes enriched the atmosphere with oxygen during the Archean and Proterozoic eras, starting about 2.5 billion years ago and continuing into the early stages of the Proterozoic era. This process, known as the Great Oxidation Event, was a significant turning point in Earth's history, leading to the rise of oxygenic photosynthesis and the oxygenation of the atmosphere.
Yes. There is one planet with oxygen in its atmosphere: our home planet Earth.
Both Saturn and Earth have atmospheres primarily composed of molecular hydrogen and helium, but Earth's atmosphere also contains significant amounts of oxygen, nitrogen, and other trace gases that support life. Additionally, both atmospheres support weather systems, such as clouds and storms, driven by temperature variations.
Yes, a vein holds oxygen enriched blood. An artery holds deoxygenated blood.

Mercury, Venus, Mars, and the gas giants Jupiter, Saturn, Uranus, and Neptune do not have oxygen in their atmospheres. These planets have atmospheres composed of different elements and compounds, but oxygen is not a significant component.
An atmosphere is considered oxygen-enriched when it contains more than 21% oxygen by volume. Levels higher than this can present safety hazards due to the increased risk of fire and may require monitoring or ventilation.
No, normal human senses cannot detect an oxygen-enriched atmosphere, as our senses do not have the ability to directly detect or measure the percentage of oxygen in the air. Specialized equipment is needed to accurately measure the oxygen content in an atmosphere.

Earth is the only planet known to have a significant amount of oxygen molecules in its atmosphere.
There is little difference between controlled and modified atmospheres. They both refer to atmospheres where the proportions of the normal gaseous/vapor components oxygen, nitrogen, carbon dioxide and water vapor, are modified to achieve some storage/packaging goal. This is commonly lowering the oxygen and/or increasing the carbon dioxide. All such atmospheres are modified atmospheres, they become controlled atmospheres when an attempt is made to regulate the composition of one or more of component gases.
