Describe oxygen cycle in nature?
Oxygen is produced through photosynthesis by plants, algae, and some bacteria. During this process, carbon dioxide is converted into oxygen using sunlight. Oxygen is then released into the atmosphere and is used by organisms for respiration, where it is converted back into carbon dioxide. This cycle helps to maintain the balance of oxygen and carbon dioxide in the atmosphere.
What is the approximate percentage of oxygen in the atmosphere?
Earth's atmosphere is about 21% oxygen by volume (for dry air).
How does oxygen stay around earth and not float into space?
Oxygen is held close to Earth by gravity, which creates a force that pulls gases toward the planet's surface. The Earth's atmosphere acts as a protective barrier that helps keep oxygen from escaping into space. Additionally, the planet's magnetic field also helps to shield the atmosphere from the solar wind that could strip away gases.
What happen when higher energy ultraviolet radiations act on the oxygen at the higher level of the atmosphere?
When higher energy ultraviolet radiations act on oxygen at higher levels of the atmosphere, they can break apart oxygen molecules (O2) into two individual oxygen atoms. These oxygen atoms can then combine with other oxygen molecules to form ozone (O3) through a series of reactions. This process is important for the formation of the ozone layer, which helps protect Earth from harmful UV radiation.
What is the gas in the atmosphere that fires require to burn?
Oxygen is the gas in the atmosphere that fires require to burn. It helps in the combustion process by reacting with the fuel source, releasing heat and light in the process.
Does photosynthesis add oxygen to the atmosphere?
Yes, photosynthasis does add oxygen to the atmosphere becaause the organisms (plants) developed the ability to photosynthasise. By taking in carbon dioxide and releasing oxygen.
What source removes carbon dioxide from the atmosphere?
Plants and trees, they convert it to oxygen
What component of the earths atmosphere exists as a result of photosynthesis?
Oxygen is the component of the Earth's atmosphere that exists as a result of photosynthesis. During photosynthesis, plants and other photosynthetic organisms release oxygen as a byproduct. This process helps to replenish and maintain the oxygen levels in the atmosphere, supporting aerobic life forms.
What changed your formerly poisonous atmosphere into an oxygen rich atmosphere?
The development of photosynthetic organisms, such as cyanobacteria and plants, played a significant role in changing Earth's atmosphere to oxygen-rich. These organisms released oxygen as a byproduct of photosynthesis, gradually increasing the oxygen levels in the atmosphere over millions of years.
What give off oxygen to the atmosphere?
Plants, algae, and cyanobacteria release oxygen into the atmosphere as a byproduct of photosynthesis. These organisms use carbon dioxide, water, and sunlight to produce oxygen and glucose, which helps sustain life on Earth.
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.
When photosynthesis take place the plant gives off?
When photosynthesis takes place, plants give off oxygen as a byproduct. Oxygen is released into the atmosphere through small pores in the plant's leaves called stomata. This process helps to replenish and maintain the oxygen levels in the atmosphere.

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 did the development of ozone in the stratosphere and oxygen in the atmosphere help do?
Development of ozone layer helps to avoid the UV from entering.
What is another form of the element oxygen that is beneficial in the upper atmosphere?
Ozone (which is O3). It helps protect from ultraviolet light.
