Nitrogen makes up approx. 80% of the atmosphere.
What else can I help you with?
Which gas became part of earth's atmosphere mainly as a result of the evolution of life-forms?
Oxygen became a significant part of Earth's atmosphere due to the evolution of photosynthetic life forms, such as cyanobacteria and plants. These organisms produce oxygen as a byproduct of their metabolic processes, leading to the rise of oxygen levels in the atmosphere over time.
Is Earth's crust part of the atmosphere?
No, earth's crust is not part of the atomosphere.
Is magnetosphere a part of the earth's atmosphere?
No, the magnetosphere is not part of the Earth's atmosphere. It's the region surrounding the Earth where the planet's magnetic field interacts with solar winds. The atmosphere is the layer of gases that surrounds the Earth.
Is nitrogen the main part of earth's atmosphere?
Yes, Earth's atmosphere is about 78% nitrogen.
What gas became part of Earths atmosphere mainly as a result of the evolution of life-forms?
Oxygen became part of Earth's atmosphere mainly as a result of the evolution of life forms, particularly through photosynthesis by early cyanobacteria and plants. This process involved converting carbon dioxide into oxygen as a byproduct, leading to the oxygen-rich atmosphere we have today.
What part of the atmosphere is least dense?
The exosphere is the least dense part of the earth's atmosphere.
The atmosphere is one part of the geosphere?
no,because atmosphere is not part of the earth. Geosphere is a land or a solid part.
Why doesn't Earth's atmosphere extend completely out into space?
The Earth's atmosphere is kept in place by gravitational pull the Earth exerts on particles in the atmosphere. But part of the Earth's atmosphere does float out into space. The part that is lost out into space is the extremely light particles like Hydrogen which can escape the Earth's gravity.
Are the five layers of the atmosphere in earth or out of earth?
The five layers of the Earth's atmosphere are within the Earth, as part of the planet's atmosphere. These layers include the troposphere, stratosphere, mesosphere, thermosphere, and exosphere.
Which part of earth is largest?
mantle
Why have astronomers built the largest optical telescopes on the top of mountains?
To get above the thickest part of the Earth's atmosphere. The air absorbs light and its movements distort the image.
What is the part of the Earth that is covered by air?
Atmosphere
