How the classification of a fine-grained soil as either a silt or a clay is done?

What is meant by the shear strength of soils? O A. Shear strength of a soil is its internal resistance to deformations. B. Shear strength of a soil is its iexternal resistance to shearing stresses. O C. Shear strength of a soil is its internal resistance to shearing strains. O D. Shear strength of a soil is its internal resistance to shearing stresses. QUESTION 14 Some soils show a peak shear strength? O A. These soils are generally firm (e.g. normally consolidated clays) and the confining stresses are large enough to suppress O B. These soils are generally dense and are large enough to O C. These soils are generally dense (e.g. dense sands and overconsolidated clays) and the confining stresses are not large enough to suppress dilation. O D. These soils are generally LOOSE (e g. loose sands and underconsolidated clays) and the confining stresses are large enough to suppress dilation. suppress dilation. dilation.

Explain why we seperate soil into two categories
