It is unsure were the first oxygen molecule came from came from, but my bet was that it was from the process "Outgassing" in which Water, Carbon Dioxide, and other fluids, were spewed out of volcanoes. The Carbon Dioxide was used by Cyanobacteria, or Stromatolites(sp?),in photosynthesis, thus producing oxygen.
What else can I help you with?
Where did the oxygen in Earth's atmosphere come from originally?
The oxygen in Earth's atmosphere originally comes from the process of photosynthesis carried out by early photosynthetic organisms like cyanobacteria, which released oxygen as a byproduct. Over time, the accumulation of oxygen led to the development of an oxygen-rich atmosphere.
Billions of years ago how did the earth come to have an oxygen rich atmosphere?
The oxygen in Earth's atmosphere was likely produced around 2.4 billion years ago by photosynthetic organisms such as cyanobacteria, which released oxygen as a byproduct of photosynthesis. Over time, this oxygen accumulated in the atmosphere, leading to the development of an oxygen-rich environment.
How did Earth come to have an oxygen atmosph?
Earth's oxygen atmosphere was primarily created by early photosynthetic organisms, such as cyanobacteria, which converted carbon dioxide into oxygen as a byproduct of photosynthesis. Over millions of years, these organisms accumulated oxygen in the atmosphere, resulting in the oxygen-rich environment we have today.
How did oxygen become a part of earth's atmosphere and what did this increase in oxygen levels allow?
The majority of oxygen in the atmosphere come from photosynthesis. Aquatic Cyanobacteria (blue green algae) were the first known organisms to use photosynthesis, before there were land plants. The by product of photosynthesis is oxygen. This increase in oxygen eventually allowed organisms to use respiration as a method of energy production. Thus it allowed for land animals.
Is liquid oxygen a compound?
Oxygen (O) is an element. O2 gas is NOT an element. Its a Molecule. When two simillar atoms come together, they form molecule. When Dissimilar atoms join, they for compounds. Ex : H2O
What three atoms of oxygen come together?
Three atoms of oxygen come together to form an ozone molecule (O3). This molecule is responsible for protecting Earth by absorbing and blocking harmful ultraviolet radiation from the sun in the stratosphere.
Where does the oxygen come from in phoyosynthesis?
From the CO2 molecule.
What molecule does the oxygen gas come from?
Water
What molecule does the oxygen you bretah come from?
Oxygen is an atom. What you breath on a regular basis is O2
What molecule does oxygen come from?
Oxygen in the Earth's atmosphere primarily comes from photosynthesis, where plants and other photosynthetic organisms produce oxygen as a byproduct. During photosynthesis, these organisms use carbon dioxide and water to create glucose and release oxygen.
What two atoms of the same element come together what do they form?
When two atoms of the same element come together, they form a molecule of that element. For example, when two oxygen atoms come together, they form a molecule of oxygen (O2).
An example of a molecule?
A molecule of water, a molecule of hydrogen, a molecule of oxygen, a molecule of sugar... Actually more substances come in form of molecules than in atomic form.
Where does oxygen come from and why is it important to life on earth?
Oxygen is important as it the breathing sources. It also forms ozone which is vital for life on earth.
What molecule did the oxygen we breathe originally come from?
The oxygen we breathe comes from the process of photosynthesis in plants, where they convert carbon dioxide and water into glucose and oxygen. The oxygen gas is released as a byproduct of this reaction.
How did germs first come to earth?
They didn't come to earth they evolved here
What language did oxygen come from?
Oxygen as an element was not created by language; it is a naturally occurring element that is essential for life on Earth. Oxygen was first discovered and identified as a distinct element in the 18th century by several scientists independently.
Does o2 represent one molecule of substance?
O2 represents one molecule . the 2 comes in there to show that 2 atoms come together and make one molecule. one atom of oxygen will be written simply as O
