Question

What is the element that makes up $78\% $ of the atmosphere?

Answer 1

Hint: We have to know that, an environment, signifying 'ball' or 'circle' is a layer or a bunch of layers of gases encompassing a planet or other material body, that is held set up by the gravity of that body. A climate is bound to be held if the gravity it is liable to is high and the temperature of the environment is low.

Complete answer:
We have to see that the environment contains the air that we relax. It holds the sun's warmth and keeps it from getting away once again into space. It shields life from destructive radiation from the sun. Assume a significant part in the earth’s water cycle. It helps keep the environment on Earth moderate. There is no limit between climate and space. The air gets less thick and denser until it "mixes" into space.
The air of earth is made out of nitrogen (about $78\% $ ), oxygen (about $21\% $ ), argon (about $0.9\% $ ), carbon dioxide (about $0.04\% $ ), and different gases in the following sums. Oxygen is utilized by most life forms for breath; nitrogen is fixed by microbes, and lightning to create smelling salts utilized in the development of nucleotides and amino acids; and carbon dioxide is utilized by plants, green growth, and cyanobacteria for photosynthesis. The air assists with shielding living organic entities from hereditary harm by sun powered bright radiation, sun oriented breeze, and enormous beams. The current creation of the earth's environment is the result of billions of long stretches of biochemical change of the paleo air by living organic entities.
Therefore, nitrogen is the element that makes up $78\% $ of the atmosphere.

Note:
We have to know that when, the earth's climate does not end at a particular spot. The higher we go, the more slender the environment gets. There is no unmistakable differentiation between the climate and space. $75\% $ of the environment is inside $11$ kilometers of the Earth's surface.
