Question

1. choose two things people do that put carbon dioxide in the air. walk to school burn coal drive cars ride bikes use wind turbines 8. choose the correct answer. which statement is true? climate change prevents global warming. global warming is an example of climate change. global warming prevents climate change. global warming and climate change are the same thing.

Explanation:

Question 7

To determine which activities release carbon dioxide, we analyze each option:

• Walking to school: Does not burn fossil fuels, so no CO₂ emission.
• Burning coal: Coal is a fossil fuel; burning it releases CO₂.
• Driving cars: Cars often use fossil fuels (like gasoline), burning them releases CO₂.
• Riding bikes: No fossil fuel use, so no CO₂ emission.
• Using wind turbines: Generates clean energy, no CO₂ emission.

So the two activities are burning coal and driving cars.

• "Climate change prevents global warming": Incorrect, as climate change is related to global warming (global warming is a cause of climate change).
• "Global warming is an example of climate change": Correct. Global warming (increase in Earth's average temp due to greenhouse gases) is one aspect of climate change (long - term changes in climate patterns).
• "Global warming prevents climate change": Incorrect, global warming contributes to climate change.
• "Global warming and climate change are the same thing": Incorrect. Global warming is a part of climate change; climate change includes more aspects like changes in precipitation, wind patterns, etc.

Answer:

• burn coal
• drive cars
