Which of the following is a greenhouse gas that is released by human activities and speeds up Global Warming?
- A.
Petroleum
- B.
Natural gas
- C.
Nuclear power
- D.
Carbon dioxide
Correct Answer
D. Carbon dioxideExplanation
Carbon dioxide is a greenhouse gas that is released by human activities and speeds up global warming. When fossil fuels like petroleum and natural gas are burned, they release carbon dioxide into the atmosphere. This carbon dioxide traps heat from the sun, leading to an increase in global temperatures. Nuclear power, on the other hand, does not release carbon dioxide during its operation. Therefore, carbon dioxide is the correct answer as it is directly linked to human activities and the acceleration of global warming.Rate this question:
