Oxygen molecules in the atmosphere primarily come from plants and other photosynthetic organisms that release oxygen during the process of photosynthesis. This process involves the conversion of carbon dioxide and water into glucose and oxygen. Additionally, a smaller amount of oxygen also comes from the breakdown of carbon dioxide molecules in the upper atmosphere by solar radiation.
What else can I help you with?
Where does oxygen gas come from in photosynthesis?
The splitting of water by the process of photolysis in photosystem II. There the electrons and protons are used in the process of photosynthesis but oxygen gas is a byproduct that diffuses out of the stomata into the atmosphere.
What energy is involved in the production of large organic molecules in the primitive reducing atmosphere?
Oxygen
What do chemicals released into the atmosphere break ozone down into to?
Chemicals released into the atmosphere, such as chlorofluorocarbons (CFCs), break ozone down into oxygen molecules and chlorine atoms through a series of chemical reactions. The chlorine atoms then react with ozone molecules, leading to the depletion of the ozone layer.
What happens when higher energy UV radiations act on the oxygen at the higher level of the atmosphere?
ozone layer prevents harmful UV radiations to reach earth's atmosphere. ozone is formed at the higher level of atmosphere by the action of UV radiation on molecule. High energy UV radiations split apart some oxygen molecules into atomic oxygen which react with molecular oxygen to form ozone molecules.
How can introduction of ozone in the atmosphere be explained?
Ozone is formed in the atmosphere through reactions involving oxygen molecules and ultraviolet radiation from the sun. The process begins with the dissociation of oxygen molecules (O2) to form oxygen atoms, which then combine with other oxygen molecules to create ozone (O3). This natural ozone layer plays a crucial role in absorbing harmful ultraviolet radiation and protecting life on Earth from its damaging effects.
How does the atmosphere keep oxygen inside?
Inside what? Oxygen is part of the atmosphere. The thermal velocity of its molecules are insufficient to escape earth's gravity (unlike hydrogen molecules which are fast enough).
Where does oxygen in water come from?
Oxygen in water primarily comes from two sources: the atmosphere and photosynthesis by aquatic plants and algae. Oxygen is dissolved into water from the surrounding air, and aquatic plants and algae produce oxygen as a byproduct of photosynthesis, releasing it into the water.
Where does oxygen gas come from in photosynthesis?
The splitting of water by the process of photolysis in photosystem II. There the electrons and protons are used in the process of photosynthesis but oxygen gas is a byproduct that diffuses out of the stomata into the atmosphere.
What is a compound with two oxygen atmosphere molecule?
Carbon Dioxide (two oxygen molecules and one carbon molecule)
What are the five components of the atmosphere?
The five components of the atmosphere include nitrogen, oxygen, carbon dioxide, water vapors and other gaseous molecules. Nitrogen and oxygen make up most of the atmosphere.
Most of the atmospheric oxygen occurs as a result of photosynthesis From which of the following molecules is the oxygen derived?
The oxygen in photosynthesis is derived from water.
How is ozone produced in the upper atmosphere?
Ozone is produced in the upper atmosphere through a process called photodissociation, where ultraviolet (UV) radiation from the sun breaks apart oxygen molecules (O2) into individual oxygen atoms. These oxygen atoms then combine with other oxygen molecules to form ozone (O3).
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 formed by the interaction of lightning with oxygen?
Ozone is formed when lightning interacts with oxygen molecules in the atmosphere. Lightning breaks apart the oxygen molecules, allowing them to recombine into ozone, which is a molecule made up of three oxygen atoms.
What energy is involved in the production of large organic molecules in the primitive reducing atmosphere?
Oxygen
What are 2 molecules found in the earth's atmosphere?
oxygen (O2) and carbon dioxide (CO2)
Do any other planets have oxygen in their atmospheres?
Earth is the only planet known to have a significant amount of oxygen molecules in its atmosphere.
