What was Earths atmosphere before photosynthesis?
It was like a cow in water, and a dove giving birth...
Earths early atmosphere was changed dramatically by the evolution of?
photosynthetic organisms, like cyanobacteria, which produced oxygen as a byproduct of photosynthesis. This led to the increase in atmospheric oxygen levels, changing the composition of Earth's early atmosphere.
How would earths atmosphere be different if organisms capable of photosynthesis not evolved?
It will remain as reductive atmosphere. Ther will be only gases like NH3, H2 , H2S. H2O. There would be no life
Was least likely to have been a component of Earths atmosphere before life began?
oxygen
What was the earth's atmosphere before like photosynthesis?
Before photosynthesis, the Earth's atmosphere was primarily composed of carbon dioxide and nitrogen, with very little oxygen. The emergence of photosynthetic organisms led to an increase in atmospheric oxygen levels over time.
What added oxygen to earths early atmosphere?
The primary sources of oxygen in Earth's early atmosphere were likely photosynthetic organisms like cyanobacteria, which began producing oxygen as a byproduct of photosynthesis. Over time, this oxygen built up in the atmosphere, leading to the development of oxygen-rich conditions on Earth.
How was oxygen added to the earths atmosphere?
Oxygen was added to Earth's atmosphere through the process of photosynthesis by early photosynthetic organisms like cyanobacteria. These organisms released oxygen as a byproduct, which accumulated over millions of years and eventually led to the oxygen-rich atmosphere we have today.
Does mercury have an atmosphere that is very similar to earth's atmosphere?
mercury has no atmosphere which means it is nothing like earths.
What was earth's atmosphere like before photosynthesis?
Before photosynthesis, Earth's atmosphere was primarily composed of carbon dioxide, methane, ammonia, and water vapor. There was very little oxygen present. The emergence of photosynthetic organisms over billions of years dramatically altered the composition of the atmosphere to include more oxygen and less carbon dioxide.
What created earths early atmosphere?
Earth's early atmosphere was created by gases released from volcanic activity, such as water vapor, carbon dioxide, nitrogen, and small amounts of methane. Over time, the atmosphere evolved through processes like photosynthesis by early organisms, which contributed oxygen and transformed the composition of the atmosphere to what it is today.
What is earths atmospere like?
The atmosphere is a invisable line across the Earth.
Is krypton a gas in earths atmosphere?
Yes. Superman doesn't like it.
