Worked Solution & Example Answer:A scientist produced the information in Figure 6 about the Earth’s atmosphere and the Earth’s average surface temperature - Edexcel - GCSE Chemistry Combined Science - Question 3 - 2023 - Paper 2
Step 1
Complete the bar chart showing the composition of the Earth’s atmosphere 3 billion years ago
Answer
To complete the bar chart for the Earth's atmosphere 3 billion years ago, we need to indicate the percentage of carbon dioxide, which is given as 95%.
- Locate the 'carbon dioxide' category on the x-axis of the bar chart.
- Draw a bar that reaches the 95% mark on the y-axis to represent the high concentration of carbon dioxide in the early atmosphere.
This accurately reflects the data presented in Figure 6.
