Soil Types and Characteristics Analysis

What are the characteristics of cohesive soils and granular cohesionless soils?

Choose the correct option:

a. Cohesive soils contain clay minerals and exhibit plasticity.

b. Granular cohesionless soils do not stick together and are non-plastic.

Answer:

a. Cohesive soils contain clay minerals and exhibit plasticity.

b. Granular cohesionless soils do not stick together and are non-plastic.

The given description refers to two types of soils: cohesive soils and granular cohesionless soils. Cohesive soils are characterized by their ability to stick together due to the presence of clay minerals. They exhibit plasticity and can be molded when wet. On the other hand, granular cohesionless soils do not have clay minerals and are composed of particles such as sand, gravel, and silt. These soils do not stick together and are non-plastic.
