Question

1. choose the correct answer. carbon dioxide might cause the atmosphere to get warmer because ____. carbon dioxide reflects sunlight carbon dioxide traps heat carbon dioxide is lost from the atmosphere carbon dioxide traps sunlight

Explanation:

To solve this, we analyze each option:

• "carbon dioxide reflects sunlight": Carbon dioxide doesn't primarily reflect sunlight to warm the atmosphere.
• "carbon dioxide traps heat": This is correct. Carbon dioxide is a greenhouse gas that traps infrared radiation (heat) in the atmosphere, leading to the greenhouse effect and warming.
• "carbon dioxide is lost from the atmosphere": If it were lost, it wouldn't cause warming, so this is incorrect.
• "carbon dioxide traps sunlight": Sunlight is mostly visible light; carbon dioxide traps heat (infrared), not sunlight directly.

Answer:

B. carbon dioxide traps heat
