Which of the following describes a cohesive soil?

Cohesive soil is characterized by its ability to retain water, which contributes to its sticky or slick feel when wet. This quality is primarily found in clay soils, which contain fine particles that can bind together, allowing them to exhibit cohesion. When moisture is present, these particles create a paste-like consistency that enhances their adhesive properties, making the soil feel slick.

Understanding the properties of cohesive soil is essential for construction and excavation projects, as it directly affects stability and the engineering of foundations. Cohesive soils typically have a lower permeability compared to sandy or granular soils, meaning they do not allow water to pass through easily. This aspect is crucial to consider when managing drainage or erosion control during excavation activities.
