584 Questions

Soil and foundation engineering questions address the physical and mechanical properties of soil critical for construction and stability. The topics include shear strength, soil compaction, void ratios, and subsurface investigation techniques. These advanced geotechnical concepts are typically evaluated in civil engineering and specialized recruitment examinations.

Multiple choice biology soil : our life soil properties soil - properties basics of soil pollution

An area of soil is thoroughly wetted and allowed to drain until capillary movement of water stopped. The water contents of the soil will give an estimate of its

  1. Capillary water

  2. Storage water

  3. Field capacity

  4. Gravitational water

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Field capacity is the capacity of field. The amount of water retained by a unit weight of undisturbed soil after complete drainage under controlled conditions is called as field capacity.
Water held up in capillary space between soil particles is called as capillary water.
Gravitational water is the water that seeps down the surface of earth and makes up the water table.
Storage water is normally not used to describe soil water.

The depth of the percolation tank is limited to the .......... of the height between bed level and full storage level.

  1. Half

  2. One fourth

  3. One third

  4. Same

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
Percolation tank is an artificially created surface water body, submerging in its reservoir a highly permeable land so that surface runoff is made to percolate and recharge the ground water storage. The size of percolation tank should be governed by percolation capacity of strata in the tank bed and the cut-off trench is to be provided below the earthen bund with depth limited to one-fourth of the height between bed level and full storage level. 
So, the correct answer is option B.

The lower percolation rate refers that the soil

  1. Can hold water for less time

  2. Can hold water for more time

  3. Cannot hold water

  4. None of the above

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Percolation rate of a soil is the water absorption rate of the soil. It depends on the composition of the soil. It is different for different types of soil. Hence, it helps in selection of proper soil for the crop growth. Soil with lower percolation has high water retention capacity whereas soil with high percolation has low water retention capacity. Lower percolation rate refers that the soil can hold water for more time while higher percolation rate refers that the soil can hold water for less time. 

Thus, the correct answer is option B.

The rate of water absorption by the soil defines the 

  1. Rate of water movement

  2. Rate of seeping

  3. Rate of percolation

  4. Rate of absorption

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Percolation rate of a soil is the rate of water absorption by the soil. It depends on the composition of the soil. It is different for different types of soil. Hence, it helps in selection of proper soil for the crop growth. Soil with lower percolation rate has high water retention capacity whereas soil with high percolation rate has low water retention capacity. 

Thus, the correct answer is option C. 

Multiple choice biology soil : our life soil properties soil - properties basics of soil pollution

The water content of soil is defined as the ratio of

  1. Volume of water to volume of voids in soil

  2. Volume of water to volume of given soil

  3. Weight of water to weight of solids of given mass of soil

  4. Weight of water to weight of air in voids

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Explanation: Water content or moisture content is the quantity of water contained in a material, such as soil (called soil moisture), rock, ceramics, fruit, or wood. The water content of soil is defined as the ratio of weight of water to weight of solids of given mass of soil.

Multiple choice biology soil : our life soil properties soil - properties basics of soil pollution

Clay has ____ permeability and ____ porosity.

  1. High - high

  2. High - low

  3. Low - high

  4. Low - low

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Explanation: Clay can have a very high porosity. Because its grains are very small, there are a lot of (small) pore spaces in between them. What clay does not have is good permeability, which is a measure of how "connected" these pore spaces are. Clay can hold a lot of water, but it doesn't let it flow very well.

Water holding capacity of clayey soil is more than sandy soil because _____.
a) Space between clay particles is more
b) Surface of clay particle is more
c) Space between sand particle is more
d) Clay particle can absorb more water
Which one of the following alternatives is correct?

  1. A, D

  2. B, D

  3. B, C

  4. C, D

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Clay soil have high water holding capacity. This is because the space between clay soil particles is higher making them possess more retention capacity. These soils can absorb more water.
