Soil Structure
1 - Question
What are the Soil properties, which are influenced by soil structure?
a) Permeability
b) Compressibility
c) Shear strength
d) All of the mentioned
View Answer
Explanation: Soil structure is an important factor which influences many soil properties such as permeability, compressibility, and shear strength.
2 - Question
The single grained structure is a characteristic of __________
a) Coarse-grained soil
b) Fine-grained soil
c) None of the mentioned
d) All of the mentioned
View Answer
Explanation: Single grained structure is usually found in coarse-grained soil.
3 - Question
Soil structure usually defines __________
a) Arrangement of soil particles and Stage of aggregation of soil particle in soil
b) Composition of the soil mass
c) None of the mentioned
d) All of the mentioned
View Answer
Explanation: Soil structure is defined as the arrangement and state of aggregation of soil particle in a soil mass.
4 - Question
An arrangement composed of ‘flocs’ of soil particle is known as __________
a) Dispersed structure
b) Cohesive matrix structure
c) Honey comb structure
d) Flocculent structure
View Answer
Explanation: An arrangement composed of ‘flocs’ of soil particle is known as flocculent structure. As the particles are oriented ‘edge-to-edge’ (or) ‘edge-to-face’ with respect to one another.
5 - Question
An arrangement composed of soil particle having a parallel orientation is ___________
a) Dispersed
b) Coarse grained skeleton
c) Honey comb
d) Single grained
View Answer
Explanation: In dispersed structure of particle are oriented face to face with one another in a dispersed state.
6 - Question
The skeleton and matrix structure represent ___________
a) Coarse-grained soil
b) Fine-grained soil
c) Composite soil
d) Loose-grained soil
View Answer
Explanation: An arrangement of coarse grains forming a skeleton and matrix represent composite soils.
7 - Question
The soil structure, having comparative loose stable structure is ____________
a) Honey comb
b) Cohesive matrix
c) Flocculent
d) Single grained
View Answer
Explanation: Honey comb structure is composed of loosely arranged bundle of particle. Hence they have comparatively less stable structure than others.
8 - Question
The honey comb, flocculent and dispersed structure are found in __________
_ a) Fine-grained soil
b) Coarse grained soil
c) Composite soil
d) All of the mentioned
View Answer
Explanation: Fine grained soil usually contains a combined structure of honeycomb, flocculent and dispersed.
9 - Question
Coarse-grain skeleton structure, consist of arrangement of __________
a) Soil forming honey comb structure
b) Coarse grain forming a skeleton
c) Soil oriented ‘edge-to-edge’ with one another
d) None of the mentioned
View Answer
Explanation: An arrangement of coarse grains forming a skeleton with its interstices partly filled by relatively loose aggregation of the finest soil grains is shown in coarse-grained skeleton structure.
