Question

the amount of carbon dioxide in the atmosphere is (a) decreasing (b) increasing (c) fixed (d) eliminated​

Answer 1

Concept

Pollution means the mixing of harmful substances in the environment. It can be done in various ways or of many types. There can be air pollution, water pollution, soil pollution, noise pollution.

To find

The amount of carbon dioxide in the atmosphere is

• increasing?
• fixed?
• eliminated?

Explanation

The amount of carbon dioxide in the atmosphere is increasing at a very fast rate. It occurs due to increase in the pollution level of the atmosphere. There are various another ways through which carbon dioxide is increasing in which one of the way is decrease in plants, tree, etc. We know that human beings inhale oxygen and exhails carbon dioxide. Plants provides oxygen and takes carbon dioxide. When plants are decreasing and the population of human beings are increasing then it is obvious that the level of carbon dioxide also increases. The level of contamination which industries put in the atmosphere also contains carbon, nitrogen which reacts with oxygen to form carbon dioxide.

Answer 2

The amount of carbon dioxide in the atmosphere is (b) increasing.

Carbon dioxide in the atmosphere:

• NASA estimates that in April 2021, the atmospheric concentration of carbon dioxide ($CO_{2}$) was at 416 parts per million (ppm).
• The fact that this level has been growing for 200 years is concerning for the environment since $CO_{2}$ is a potent greenhouse gas that traps heat.
• Because it is one of the gases in the atmosphere that causes the greenhouse effect, which causes the Earth to warm, carbon dioxide is known as a greenhouse gas.
• An essential greenhouse gas that aids in keeping the heat in our atmosphere is carbon dioxide.
• Our earth would be uninhabitable cold without it.
• However, a rise in average global temperatures brought on by rising $CO_{2}$ levels in our atmosphere is affecting other facets of Earth's climate.
