Multiple choice social science water: a precious resource water table groundwater and depletion of water table the water cycle

A man digging the ground near a water body found that the soil was moist.As he kept digging deeper and deeper he reached a level where all the spaces between particles of soil and gaps between rocks were filled with water. The upper limit of this layer is called:

  1. water level

  2. ground water

  3. water table

  4. water limit
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The upper limit of this layer where water is present between particles of soil and gaps between rocks is called water table and water below the layer is called groundwater.

Multiple choice botany water absorption and ascent of sap in plants apoplast and symplastic pathway transport of water in plants water transport

The amount of water held by the soil after drainage is known as

  1. Mineral water

  2. Soil water

  3. Field capacity

  4. Gravitational capacity
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Gravitational water percolates the soil layers and reaches the water table and not available by soil for plants. The amount of water retained by soil and available for plants is called field capacity. Thus, the correct option is C.

Multiple choice

What are the limitations of gully plugging as a soil conservation method?

  1. It is effective in all types of soil conditions

  2. It is a permanent solution to gully erosion

  3. It is cost-effective and easy to implement

  4. It may not be suitable for large and deep gullies
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Gully plugging may not be suitable for large and deep gullies, as it may require extensive resources and engineering expertise to construct stable and effective gully plugs.

Multiple choice

The ability of soil to hold and release water for plant use is referred to as:

  1. Water-holding capacity

  2. Permeability

  3. Infiltration rate

  4. Bulk density
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Water-holding capacity refers to the ability of soil to hold and release water for plant use.

Multiple choice

What is the primary factor that determines the shear strength of a soil?

  1. Cohesion

  2. Friction

  3. Density

  4. Water content
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Cohesion is the primary factor that determines the shear strength of a soil. It is the force that holds soil particles together and resists shear deformation.

Multiple choice

What is the angle between the failure plane and the major principal stress direction in a soil?

  1. Angle of internal friction

  2. Angle of repose

  3. Angle of shear resistance

  4. Angle of critical state
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The angle of shear resistance is the angle between the failure plane and the major principal stress direction in a soil.

Multiple choice

What is the maximum shear stress that a soil can withstand before failure?

  1. Shear strength

  2. Cohesion

  3. Friction

  4. Tensile strength
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Shear strength is the maximum shear stress that a soil can withstand before failure.

Multiple choice

What is the process of increasing the density of a soil by mechanical means?

  1. Compaction

  2. Consolidation

  3. Settlement

  4. Erosion
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Compaction is the process of increasing the density of a soil by mechanical means, such as rolling or tamping.

Multiple choice

Which soil property is responsible for the soil's ability to resist deformation under repeated loading?

  1. Resilience

  2. Compressibility

  3. Shear strength

  4. Permeability
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Resilience is the soil property responsible for the soil's ability to resist deformation under repeated loading.

Multiple choice

What is the primary factor that determines the shear strength of soils?

  1. Cohesion

  2. Friction

  3. Pore Water Pressure

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The shear strength of soils is governed by the combined effect of cohesion, friction, and pore water pressure.

Multiple choice

Which failure criterion is commonly used to represent the shear strength of soils?

  1. Tresca Failure Criterion

  2. Mohr-Coulomb Failure Criterion

  3. Rankine Failure Criterion

  4. Prandtl Failure Criterion
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The Mohr-Coulomb Failure Criterion is widely employed to describe the shear strength of soils due to its simplicity and effectiveness in capturing the behavior of various soil types.

Multiple choice

What is the relationship between the shear strength of soils and the angle of internal friction?

  1. Directly proportional

  2. Inversely proportional

  3. No relationship

  4. Depends on the soil type
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The shear strength of soils is directly proportional to the angle of internal friction, indicating that soils with higher friction angles possess greater shear strength.
