How does the atmosphere act as a blanket?

Explanation

**Step-by-Step Solution:**

1. **Understanding the Atmosphere**: The atmosphere is a layer of gases surrounding the Earth. It plays a crucial role in maintaining the conditions necessary for life.

2. **Temperature Regulation**: One of the primary functions of the atmosphere is to regulate the Earth's temperature. It helps to keep an average temperature that is suitable for living organisms.

3. **Heat Retention**: During the day, the Earth absorbs sunlight and warms up. At night, the surface of the Earth cools down. The atmosphere acts like a blanket by trapping some of this heat, preventing it from escaping into space. This process is known as the greenhouse effect.
