Step 1
Complete the bar chart showing the composition of the Earth's atmosphere 3 billion years ago by adding a bar to show the percentage of carbon dioxide.
Answer
To complete the bar chart for the percentage of carbon dioxide in Earth's atmosphere 3 billion years ago:
- Note the given percentage: Carbon dioxide was 95%.
