What is the simple meaning of greenhouse effect?

Answer and explanation

Correct answer: Trapping of heat in the atmosphere

The governing concept is atmospheric heat retention. The greenhouse effect occurs when certain gases, including carbon dioxide, methane, and water vapour, absorb and re-emit outgoing infrared radiation, so some heat remains in the atmosphere instead of escaping directly into space. The natural effect helps maintain a temperature suitable for life; an enhanced effect can cause additional warming. Drying a river, counting trees, and recycling paper may relate to environmental topics, but none defines this process. Therefore, option D is correct.
