Answer:
Rainfall is an important factor that controls the fertility of the soil. The area in which the rate of evaporation is high, those are more prone to rainfall. It provides water that is essential for the plants to grow, whose roots are at up to various depth under the soil. This water helps the plants to synthesize their food by taking in water and carbon dioxide, which is commonly known as the photosynthesis process.
During rainfall, the raindrops continuously hits the soil at different intensities and lead to the degradation of the soil quality. Excessive rainfall results in the rapid impacts between raindrops and soils, that washes away the essential nutrients present in the soil. This results in the erosion of these soil minerals.
Hence, raindrops are considered particularly to be damaging elements to the soil.
