Step 1
Complete the bar chart showing the percentage of carbon dioxide
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 given for carbon dioxide is 95%.
- Identify the scale of the bar chart on the vertical axis, which ranges from 0 to 100.
- Draw a bar for carbon dioxide that reaches up to 95 on the scale. Ensure the bar is clearly labeled as 'carbon dioxide'.
This visual representation will effectively show the dominant presence of carbon dioxide in the Earth's early atmosphere.
