- 0.075 mm to 4.75 mm
- 4.75 mm to 75 mm
- 75 mm to 300 mm

- Liquid Limit (LL)
- Plastic Limit (PL)
- Shrinkage Limit (SL)
- Optimum Moisture Content (OMC)

The angle of internal friction (φ) in soil mechanics represents:
- The angle at which a soil fails under shear stress
- The angle of repose of a soil
- The angle between the major and minor principal stresses
- The angle of settlement of a soil
The process of compacting soil to increase its density and reduce its void ratio is known as:
- Compaction
- Consolidation
- Settlement
- Shearing
The maximum dry density (ρ_dmax) of a soil is the:
- Highest density achievable through compaction
- Density of soil at its natural state
- Density of soil at its saturated state
- Density of soil at its optimum moisture content
The permeability of a soil is a measure of its ability to:
- Allow water to flow through it
- Resist shear stress
- Withstand compression
- Retain moisture
The specific gravity (G_s) of a soil particle is defined as the ratio of its:
- Mass to its volume
- Mass to the mass of an equal volume of water
- Volume to its mass
- Volume to the volume of an equal mass of water
The void ratio (e) of a soil is the ratio of:
- Volume of voids to the volume of solids
- Volume of solids to the volume of voids
- Mass of solids to the mass of voids
- Mass of voids to the mass of solids
The degree of saturation (S) of a soil is the ratio of:
- Volume of water to the volume of voids
- Volume of voids to the volume of water
- Mass of water to the mass of solids
- Mass of solids to the mass of water
The consolidation of soil involves:
- Reduction in soil volume due to applied stress
- Increase in soil volume due to applied stress
- Change in soil consistency due to applied stress
- Change in soil permeability due to applied stress
The coefficient of consolidation (c_v) is a measure of:
- Rate of consolidation of a soil
- Compressibility of a soil
- Permeability of a soil
- Shear strength of a soil
The preconsolidation pressure (p_c) of a soil is the:
- Maximum pressure the soil has experienced in its history
- Pressure at which the soil reaches its maximum dry density
- Pressure at which the soil fails under shear stress
- Pressure at which the soil reaches its liquid limit
The bearing capacity of a soil is its ability to:
- Support a load without failure
- Allow water to flow through it
- Resist shear stress
- Consolidate under applied stress
