What is the primary (most abundant) gas in the Earths atmosphere?
The primary gas in Earth's atmosphere is nitrogen, accounting for about 78% of the total atmospheric composition.
What was the chemical makeup of the atmosphere during the Jurassic period?
During the Jurassic period, the atmosphere was primarily composed of nitrogen, carbon dioxide, and oxygen, similar to the composition of the modern-day atmosphere.
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.
The primary source of earths atmosphere is?
The primary source of Earth's atmosphere is outgassing from volcanic activity and the release of gases from Earth's interior. This process began billions of years ago and continues to contribute to the composition of our atmosphere.
What plays a main role in forming earths atmosphere?
The main components of Earth's atmosphere are nitrogen (about 78%) and oxygen (about 21%). Other gases, such as carbon dioxide, methane, and water vapor, also play important roles in the composition and function of the atmosphere. Factors such as geologic processes, biological activity, and human activities influence the composition and dynamics of the atmosphere.
What is the makeup of earths atmosphere?
Gases
Why is earths composition of earths atmosphere important?
The Chemical Composition of the Earth's atmosphere is important because it holds the Earth together.
