Question
Assertion: CO2 is a major greenhouse gas.
Reason: Increase in CO2 level leads to decrease in Earth’s temperature.
- Both assertion and reason are true, and reason is the correct explanation of assertion.
- Both assertion and reason are true, but reason is not the correct explanation of assertion.
- Assertion is true, but reason is false.
- Assertion is false, but reason is true.
The correct answer is: Assertion is true, but reason is false.
- Carbon dioxide is widely reported as the most important anthropogenic greenhouse gas because it currently accounts for the greatest portion of the warming associated with human activities.
- When there's more CO2 in the atmosphere, it makes the atmosphere warmer by trapping heat. Since humans are adding more CO2 to the atmosphere, that helps explain why temperatures are increasing around the world.
- Both assertion and reason are true, and reason is the correct explanation of assertion.
