Briefly explain the greenhouse effect and one common misconception about it.

## The Greenhouse Effect The greenhouse effect is a natural process where certain gases in Earth's atmosphere (like carbon dioxide, water vapor, and methane) trap heat from the sun. These gases allow sunlight to pass through but absorb and re-emit infrared radiation, warming the planet's surface. Without this effect, Earth would be about 33°C (59°F) colder and largely uninhabitable. ## Common Misconception **Misconception:** The greenhouse effect works like an actual greenhouse, where glass traps warm air inside. **Reality:** Atmospheric greenhouse gases don't physically trap air. Instead, they absorb and re-radiate heat energy (infrared radiation) back toward Earth's surface. A real greenhouse stays warm mainly by preventing hot air from escaping through convection, which is a different mechanism entirely. The atmospheric process is purely about radiation absorption and emission.
