Question

statement a: if fossil fuel burning increases, then atmospheric co₂ will increase. statement b: the increase in atmospheric co₂ is due to an increase in the amount of fossil fuels that are being burned. a statement a b statement b

Explanation:

Statement A is a conditional statement expressing a cause - effect relationship. Statement B is a statement of causation. Fossil fuel burning releases carbon - dioxide into the atmosphere. Both statements are correct based on scientific knowledge about the carbon - cycle and the role of fossil fuels.

Answer:

Both statements are correct. There is no option provided in the question to select from like "a. Statement A" or "b. Statement B" as the correct one since both are valid in the context of the relationship between fossil fuel burning and atmospheric CO₂ increase. If we had to choose from the given options strictly as presented in the format of the question without considering the overall correctness, we would need more context on what the task exactly is (e.g., which is a better - worded statement etc.). But based on scientific fact, both are accurate statements about the relationship between fossil fuel burning and atmospheric CO₂ levels.
