What is soil carried by flowing water called, which is considered good for farmland?

• A. Loam
• B. Clay
• C. Alluvium
• D. Silt

Answer: (C)

Soil carried by flowing water, known as alluvium, is particularly significant for its fertility and agricultural value. Alluvium consists of sediments deposited by rivers, streams, and floodwaters, which often include a mixture of sand, silt, clay, and organic matter. This nutrient-rich soil is typically found in floodplains and river valleys, making it ideal for farming because it replenishes the nutrients in the soil, leading to higher crop yields.

While loam is a rich soil type ideal for agriculture, it is not specifically defined by its transport by water like alluvium. Similarly, clay and silt are components of soil, but they do not encompass the full range of sedimentary materials that characterize alluvial deposits. The distinctiveness of alluvium lies in its formation process associated with flowing water, which differentiates it from other soil types that might not be transported by water.
