Explain the following:
The basement of a house usually remains cool during summer.

Explanation

**Step-by-Step Solution:**

1. **Understanding the Environment**: The basement of a house is typically located below ground level, surrounded by soil on all sides. This positioning plays a crucial role in temperature regulation.

2. **Heat Transfer Mechanism**: During summer, the sun's rays heat the surface of the earth and the walls of the house. This process is primarily due to solar radiation, which increases the temperature of these surfaces.

3. **Properties of Soil**: Soil is known to be a poor conductor of heat (a bad conductor). This means that it does not transfer heat efficiently. As a result, the heat from the warm surface does not easily penetrate into the basement.
