Define liquid soil, plastic soil, and solid soil?

Liquid soil refers to soil that is saturated with water and has a high water content, making it very fluid and easily deformable.

Plastic soil refers to soil that has a high clay content and can be easily molded or shaped when wet, but becomes hard and compacted when dry.

Solid soil refers to soil that is well-compacted and has a low water content, making it firm and stable.

Liquid Soil

- Consists of inorganic clays and organic matter
- Contains a high percentage of fine particles that are saturated with water
- Soft and has a low bearing capacity
- Can easily deform under load and flow like a liquid
- Found in areas with poor drainage or high water tables

Plastic Soil

- Consists of fine-grained particles, such as clay and silt
- Contains less water than liquid soil but still has a high moisture content
- Soft and pliable, but has some strength
- Can be molded into shapes and retains its form
- Found in areas with moderate drainage

Solid Soil

- Consists of coarse-grained particles, such as sand and gravel
- Contains less water than plastic soil and has a low moisture content
- Hard and firm
- Cannot be molded and does not deform easily
- Found in areas with good drainage or in dry regions
