The correct answer is: C.A natural process where gases trap heat in the atmosphere.

Here’s a breakdown of what the greenhouse effect is and why the other options are less accurate:

Greenhouse Effect:

The greenhouse effect is a natural process where certain gases in the Earth's atmosphere, such as carbon dioxide (CO₂), methane (CH₄), and water vapor (H₂O), trap heat from the Sun. This process is crucial because it keeps our planet warm enough to support life. Without the greenhouse effect, the Earth’s average temperature would be about 33°C (59°F) cooler, making it too cold to sustain most forms of life.

Why the other options are incorrect:

A.A man-made process where gases trap heat in the atmosphere: This describes the enhanced greenhouse effect, which is caused by the increased concentration of greenhouse gases due to human activities, such as burning fossil fuels, deforestation, and industrial processes. This enhanced greenhouse effect contributes to global warming and ...
