Which soil type typically has high susceptibility to erosion?

Fine textured soils, which are composed predominantly of small particles such as clay, have a high susceptibility to erosion due to their physical and chemical properties. These soils can easily become saturated with water, leading to reduced structural integrity and increased vulnerability to erosion from wind and water. When saturated, fine textured soils may form a slick, compact surface that can be easily washed away during heavy rainfall. Furthermore, they tend to have less cohesion and can become unstable, especially on slopes, increasing their likelihood of erosion.

In contrast, medium textured soils strike a balance between moisture retention and drainage, often exhibiting better stability against erosion. Coarse textured soils, consisting of larger particles like sand, generally allow water to drain quickly through them, which can reduce erosion risk but can also lead to nutrient leaching. Pebbly soils might similarly offer improved resistance to erosion due to their larger particle size, which helps maintain soil structure.

Thus, while different soil textures have varying levels of susceptibility, fine textured soil is particularly prone to erosion, making it the correct choice in this context.
