Without the atmosphere, which statement about weather would be most accurate?

• A. There would be no weather.
• B. More rain would occur.
• C. The sky would be permanently cloudy.
• D. Wind would be stronger.

Answer: (C)

Weather comes from the atmosphere’s moving air and its ability to carry water vapor, form clouds, and transfer heat. If the atmosphere were removed, those atmospheric processes would disappear, so the usual weather events—wind, rain, changing cloud cover—would not occur. The statement that the sky would be permanently cloudy matches the idea that, without the atmosphere to drive changing weather and clear skies, the sky would stay in a cloud-like, unchanged state. The other options hinge on weather phenomena that require air and moisture movement, which wouldn’t exist in a vacuum.
