Answer 1

Explanation:

An atmosphere (from Ancient Greek ἀτμός (atmos), meaning 'vapour', and σφαῖρα (sphaira), meaning 'ball' or 'sphere'[1][2]) is a layer or a set of layers of gases surrounding a planet or other material body, that is held in place by the gravity of that body. An atmosphere is more likely to be retained if the gravity it is subject to is high and the temperature of the atmosphere is low.

The atmosphere of Earth is composed of nitrogen (about 78%), oxygen (about 21%), argon (about 0.9%), carbon dioxide (0.04%) and other gases in trace amounts.[3] Oxygen is used by most organisms for respiration; nitrogen is fixed by bacteria and lightning to produce ammonia used in the construction of nucleotides and amino acids; and carbon dioxide is used by plants, algae and cyanobacteria for photosynthesis. The atmosphere helps to protect living organisms from genetic damage by solar ultraviolet radiation, solar wind and cosmic rays. The current composition of the Earth's atmosphere is the product of billions of years of biochemical modification of the paleoatmosphere by living organisms.

The term stellar atmosphere describes the outer region of a star and typically includes the portion above the opaque photosphere. Stars with sufficiently low temperatures may have outer atmospheres with compound molecules.

Answer 2

Answer:

1. Nitrogen it is present almost 78% in earth atmosphere and it plays a major role for the living things on earth. Nitrogen is absorbed by plants in order to process metabolic and other major activities.
2. Oxygen it constitutes over 21% of earth atmosphere, it is considered the most important gas which is present on earth for humans and plants and animals too
3. Carbon Di oxide it is present at a percentage of .03% in the atmosphere but still it is consumed by plants

some other gases are

• helium
• argon
• hydrogen
• methane
• crypton
• dust particles✌️
