gas	percentage (%)
oxygen (o )	21%
argon (ar)	0.93%
carbon dioxide (co )	0.04%
other gases	0.03%	insert your circle graph in the box below. 1. which gas makes up the largest portion of the earths atmosphere? ____________ 2. what is the second most abundant gas in the atmosphere? __________ 3. how much more nitrogen is there than oxygen in the air? ____________ 4. why do you think carbon dioxide is important even though it makes up only 0.04% of

Explanation:

Step1: Analyze the gas - percentage data

We have the percentages of different gases in air: Nitrogen (78%), Oxygen (21%), Argon (0.93%), Carbon - Dioxide (0.04%), Other Gases (0.03%).

Step2: Answer question 1

By comparing the percentages, we can see that nitrogen has the highest percentage (78%). So the gas that makes up the largest portion of the Earth's atmosphere is nitrogen.

Step3: Answer question 2

The second - highest percentage is 21% which belongs to oxygen. So the second most abundant gas in the atmosphere is oxygen.

Step4: Answer question 3

To find out how much more nitrogen there is than oxygen, we subtract the percentage of oxygen from the percentage of nitrogen. $78 - 21=57$. So there is 57% more nitrogen than oxygen in the air.

Step5: Answer question 4

Carbon - dioxide is important because it is a greenhouse gas. It absorbs and emits infrared radiation, which helps to regulate the Earth's temperature. Also, it is used by plants in the process of photosynthesis to produce oxygen and organic compounds.

Answer:

1. Nitrogen
2. Oxygen
3. 57%
4. It is a greenhouse gas and is used in photosynthesis.
