Algae and later plants used sunlight to convert water and carbon dioxide into carbohydrates and oxygen. Until about the middle of the Paleozoic oxygen went into the atmosphere faster than it could be removed.
Photosynthesize.
Plankton gives more oxygen to the atmosphere.
No it isn't. We still have about 21% oxygen content in the atmosphere.
No. Earth's atmosphere is a mixture, mostly comprised of nitrogen and oxygen.
the atmosphere is made of carbon dioxide and other gases e.g. oxygen and carbon dioxide

Oxygen did not accumulate in the atmosphere until approximately 1.5 billion years after life appeared on Earth because early organisms did not produce oxygen as a byproduct of photosynthesis. It took a few billion years for oxygen-producing cyanobacteria to evolve and become abundant, resulting in the significant accumulation of oxygen in the atmosphere known as the Great Oxidation Event.
Oxygen accumulated in Earth's atmosphere through the process of photosynthesis carried out by early cyanobacteria. These organisms released oxygen as a byproduct, gradually building up oxygen levels in the atmosphere over millions of years.
Typically passing electricity through tap water will begin to separate the hydrogen and oxygen in H2O. Oxygen bubbles will begin to accumulate at the positive contact and hydrogen to accumulate at the negative contact.
It is believed that the early Earth's atmosphere did not contain significant amounts of oxygen. Oxygen began to accumulate in the atmosphere around 2.4 billion years ago due to the emergence of photosynthetic organisms.
Oxygen began to accumulate in Earth's atmosphere around 2.4 billion years ago during the Great Oxidation Event. This was a gradual process that took hundreds of millions of years as photosynthetic bacteria started producing oxygen through photosynthesis.
Iron was the oxidized metal that caused substantial quantities of oxygen to accumulate in Earth's atmosphere, a process known as the Great Oxidation Event. This event occurred around 2.4 billion years ago as photosynthetic organisms began producing oxygen through photosynthesis, which reacted with iron in the oceans and rocks, leading to the buildup of oxygen in the atmosphere.
Oxygen began to accumulate in Earth's atmosphere approximately 2.4 billion years ago during the Great Oxidation Event, brought about by the emergence of photosynthetic organisms that produced oxygen as a byproduct of photosynthesis.
Yes, before photosynthesis evolved, oxygen was rare in Earth's atmosphere. Early Earth's atmosphere was composed mainly of carbon dioxide, nitrogen, and water vapor. As photosynthesis evolved and became more widespread, oxygen began to accumulate in the atmosphere, leading to the oxygen-rich environment we have today.
Oxygen was not present in the Earth's atmosphere 3.6 billion years ago. The atmosphere at that time was primarily composed of carbon dioxide, nitrogen, methane, and water vapor. Oxygen began to accumulate in the atmosphere around 2.5 billion years ago as a result of photosynthetic organisms.
Oxygen was least likely to have been a component of Earth's atmosphere before life began. It was initially scarce, and the atmosphere was primarily made up of gases such as methane, ammonia, water vapor, and carbon dioxide. Oxygen started to accumulate in the atmosphere following the emergence of photosynthetic organisms.
Billions of years ago, Earth's early atmosphere likely contained little to no oxygen. Oxygen began to accumulate in the atmosphere around 2.5 billion years ago due to the process of photosynthesis by early cyanobacteria and other organisms, which produced oxygen as a byproduct. This led to the gradual build-up of oxygen levels in the atmosphere over millions of years.
