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.

Describe how did oxygen come to make up to 21 percent of earths present atmosphere?
Oxygen accumulates in Earth's atmosphere from photosynthesis, where plants and algae convert carbon dioxide into oxygen. This process started with the emergence of photosynthetic organisms around 2.5 billion years ago, gradually increasing oxygen levels to the current 21 percent.
Where did oxygen originally come from?
Oxygen on Earth originally came from the process of photosynthesis carried out by early single-celled organisms like cyanobacteria. These organisms used sunlight to convert carbon dioxide and water into glucose, releasing oxygen as a byproduct. Over millions of years, this process accumulated oxygen in the atmosphere, leading to the oxygen-rich environment we have today.
Where does the free oxygen in Earths atmosphere come from?
The free oxygen in Earth's atmosphere primarily comes from the process of photosynthesis carried out by plants, algae, and certain bacteria. During photosynthesis, these organisms use energy from sunlight to convert carbon dioxide and water into oxygen and glucose.Approximately half of Earth's oxygen is produced by marine plants, specifically phytoplankton.
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.
What was Earths first atmosphere was created by?
The earths first atmosphere was created by the methane, carbon dioxide, sulphur oxides and water vapor that volcanoes were pumping out. Oxygen started to come in noticeable quantities once life had formed. Nitrogen is inert, so doesn't do anything.
Where did most of earths atmospheric oxygen originally come from?
Most of Earth's atmospheric oxygen originally came from photosynthesis by early cyanobacteria and other photosynthetic organisms around 2.5 billion years ago. These organisms converted carbon dioxide and water into oxygen through the process of photosynthesis, gradually increasing oxygen levels in the atmosphere.
Where does earths atmosphere come from?
Plants
Where do these main gases come from?
they come from earths atmosphere and gases
Where did the gases in the earths atmosphere come from?
Scientist theorize that bacteria with chlorophyll in them slowly but surely began to multiply. And as they did, they photosynthesized enough to create an entire atmosphere. (as you know oxygen is a byproduct of photosynthesis)
Where do most of the objects you use in you life originally come from?

What do we call pieces of stone that come into the earths atmosphere?
It is a meteorite (meteor).

Can asteroids come in earths atmosphere?
Yes. Asteroids can enter earth's atmosphere. In such an event the asteroid will probably strike earth's surface.
Where do the oxygen molecules in the atmosphere come from?
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.
