Share:
- 1Cohesion represents the soil’s inherent shear strength due to electrochemical attraction, mostly significant in clay.✓
- 2Cohesion is the critical angle at which soil fails under unconfined compression.
- 3Cohesion is only applicable for granular soils like sand and gravel.
- 4Cohesion represents the soil’s resistance due to friction between particles and is zero for clay.
Correct answer
Cohesion represents the soil’s inherent shear strength due to electrochemical attraction, mostly significant in clay.
