The heating of earth due to trapped radiation is called ...........

Explanation

**Step-by-Step Solution:**

1. **Understanding the Concept**: The question asks for the term that describes the heating of the Earth caused by trapped radiation. This concept is crucial in environmental science and relates to how certain gases affect the Earth's temperature.

2. **Identifying Key Terms**: The key terms in the question are "heating of the Earth," "trapped radiation," and "pollutants." These terms relate to the greenhouse effect, which is a natural process that warms the Earth’s surface.

3. **Recognizing Greenhouse Gases**: Greenhouse gases, such as carbon dioxide (CO2), play a significant role in this process. They absorb and emit radiation within the thermal infrared range, which leads to the warming of the Earth's atmosphere.
