The Earths atmosphere is made up of various gases. Which of the follow...
The composition of Earth's atmosphere is primarily made up of nitrogen, oxygen, and other gases. Let's break down the options and determine which one best describes the composition.
a) Oxygen-78%, Nitrogen-21%, Others-1%
b) Oxygen-60%, Nitrogen-30%, Others-10%
c) Nitrogen-78%, Oxygen-21%, Others-1%
d) Nitrogen-78%, Oxygen-21%, Carbon dioxide-1%
To determine the correct answer, we need to know the actual percentages of the gases in the atmosphere.
Nitrogen is the most abundant gas in the Earth's atmosphere, making up about 78% of the total volume. Oxygen is the second most abundant gas, comprising approximately 21% of the atmosphere. The remaining 1% consists of various other gases, such as carbon dioxide, helium, argon, and trace amounts of other gases.
Let's compare the options to the actual composition:
a) Oxygen-78%, Nitrogen-21%, Others-1%
This option states that oxygen is the most abundant gas, which is incorrect. Nitrogen should be the most abundant gas.
b) Oxygen-60%, Nitrogen-30%, Others-10%
This option also states that oxygen is more abundant than nitrogen, which is incorrect. Nitrogen should still be the most abundant gas.
c) Nitrogen-78%, Oxygen-21%, Others-1%
This option correctly states that nitrogen is the most abundant gas at 78% and oxygen is the second most abundant gas at 21%. It also includes the remaining 1% for other gases, which is accurate.
d) Nitrogen-78%, Oxygen-21%, Carbon dioxide-1%
This option only mentions carbon dioxide as the other gas, but there are actually several other gases present in the atmosphere. Therefore, this option is not the most accurate representation.
Based on the comparison, option c) Nitrogen-78%, Oxygen-21%, Others-1% is the best description of the composition of Earth's atmosphere.
In conclusion, the correct answer is option c) Nitrogen-78%, Oxygen-21%, Others-1%, as it accurately represents the composition of Earth's atmosphere.
a) Oxygen-78%, Nitrogen-21%, Others-1%
b) Oxygen-60%, Nitrogen-30%, Others-10%
c) Nitrogen-78%, Oxygen-21%, Others-1%
