climate change prevents global warming.

Explanation:

Question 9

• Analyze each option:
• Option 1: Burning fossil fuels releases CO₂, which is a greenhouse gas. Greenhouse gases trap heat, causing global warming, not cooling. So this is false.
• Option 2: Fossil fuels (like coal, oil, gas) are carbon - based. When burned, they react with oxygen to produce CO₂. CO₂ is a greenhouse gas that traps heat in the atmosphere, leading to global warming. This is correct.
• Option 3: Burning fossil fuels consumes oxygen (for combustion) and produces CO₂, not oxygen. Also, oxygen does not cause global warming. So this is false.
• Option 4: Burning fossil fuels produces CO₂, not oxygen, and CO₂ causes warming, not cooling. So this is false.

• Analyze each option:
• Option 1: Global warming is a part of climate change and contributes to it, it does not prevent climate change. So this is false.
• Option 2: Climate change refers to long - term changes in Earth's climate, including temperature, precipitation, etc. Global warming (the increase in Earth's average surface temperature) is one aspect or example of climate change. This is correct.
• Option 3: Global warming is a specific type of climate change (related to temperature increase), while climate change encompasses a broader range of changes (like changes in precipitation patterns, sea - level rise, etc.). So they are not the same thing. This is false.
• Option 4: Climate change is related to global warming (global warming drives many climate change processes), and climate change does not prevent global warming. This is false.

Answer:

B. Burning fossil fuels puts carbon dioxide in the air, which may cause global warming.
