What is the main characteristic of stratified soil?

Stratified soil is primarily characterized by its layered nature, which consists of distinct deposits of different sediments. This layering can occur due to various geological processes, such as sedimentation in bodies of water, glacial activity, or wind deposition. Each layer, or stratum, represents a different period of sediment deposition and can vary in texture, composition, and color.

The presence of these layers provides critical information about the historical processes that have shaped the soil and can indicate changes in environmental conditions over time. This stratification also influences water drainage and root penetration, making it a significant factor in soil evaluation for agricultural and ecological purposes.

Other stated options, while relating to soil characteristics, do not capture the essence of what makes stratified soil distinct. Homogeneous particle distribution refers to a uniform mixture of soil particles, compact rock layers relate to consolidated geology rather than soil per se, and the presence of organic material emphasizes biological components without addressing the critical geological structure of stratification.
