The arrangement of the following gases in the order of their abundance in the Earth’s atmosphere:
- a) Oxygen
- b) Carbon dioxide
- c) Nitrogen
- d) Argon
Answer to Problem 1MC
c) Nitrogen
a) Oxygen
d) Argon
b) Carbon dioxide
Explanation of Solution
The Earth’s atmosphere is an undetectable envelope of gas that is scarcely felt aside from when a breeze blows, or when rain or snow falls. The air is additionally in charge of the blue color of the sky, for the shades of dawn and nightfall, and for rainbows. A less apparent (yet more imperative feature) is that it facilitates climate in the living world.
Oxygen, nitrogen, and carbon dioxide are forever fundamental in the Earth’s atmosphere. The air screens out destructive, bright radiation and x-beams from the sun. It conveys vitality and water over substances on the Earth. Furthermore, by weathering rocks, it helps frame the dirt in which plants develop.
Nitrogen is the most abundant gas present in the Earth’s atmosphere; it comprises an average of 78.08% of the atmosphere. Oxygen is the second-largest gas present in the Earth’s atmosphere with an average presence of 20.95%. Argon comprises about 0.93% and carbon dioxide comprises about 0.038% in the Earth’s atmosphere.
