Rainfall patterns depend on

Options

A. the underground water table
B. the number of water bodies in an area
C. the density pattern of human population in an area
D. the prevailing season in an area

Explanation

**Step-by-Step Solution:**

1. **Understanding Rainfall Patterns**: Rainfall patterns refer to the distribution and amount of rainfall that occurs in a specific area over a certain period.

2. **Factors Influencing Rainfall**: Several factors can influence rainfall patterns, but we will focus on the most significant ones.

3. **Role of Water Bodies**: The presence of water bodies (like rivers, lakes, and oceans) is crucial. Water bodies provide moisture to the atmosphere through evaporation.

4. **Evaporation Process**: When the sun heats the water in these bodies, it evaporates, turning into water vapor. This process is essential for the formation of clouds.

5. **Condensation and Rainfall**: The water vapor rises, cools, and condenses to form clouds. When these clouds become heavy enough, they release the moisture as rainfall.

6. **Impact of Water Body Density**: Areas with more water bodies will have higher evaporation rates, leading to increased humidity and, consequently, more rainfall. Conversely, areas with fewer water bodies will experience less evaporation, lower humidity, and reduced rainfall.

7. **Conclusion**: Among the options provided, the number of water bodies in an area is the primary factor that directly affects rainfall patterns. Therefore, the correct answer is the number of water bodies in an area.
