Step 1
Complete the bar chart showing the composition of the Earth's atmosphere 3 billion years ago
Answer
To complete the bar chart, we need to represent the percentage of carbon dioxide in the Earth's atmosphere 3 billion years ago.
The percentage of carbon dioxide is given as 95%. Therefore, a bar should be added to the chart reaching 95% on the vertical scale. This will visually show the significant amount of carbon dioxide in the early atmosphere compared to other gases.
