The amount of Oxygen started to increase as more plants and animals appeared. The plants took in Carbon dioxide and gave out Oxygen. So, overtime the amount of Carbon dioxode (which was high) decreased, and oxygen increased.

Which group of organisms is most responsible for changing the compisition of earths early atmosphere?

Cyanobacteria are the group of organisms most responsible for changing the composition of Earth's early atmosphere. Through photosynthesis, they released oxygen into the atmosphere, fundamentally altering its composition and paving the way for aerobic organisms to evolve.


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.


What caused a major change in the composition of Earths atmosphere?

One major change in the composition of Earth's atmosphere was the Great Oxidation Event about 2.4 billion years ago. This event led to a significant increase in oxygen levels due to the emergence of photosynthetic organisms that released oxygen as a byproduct. This change had a profound impact on the evolution of life on Earth.


What era did earths atmosphere form in?

Earth's atmosphere formed around 4.5 billion years ago, shortly after the planet's formation. The early atmosphere likely consisted of gases such as hydrogen and helium, but has since evolved through volcanic activity and the presence of living organisms to the composition we see today.


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.
