Question

The levels of soil density are given below: (A) Saturated density
(B) Submerged density
(C) Wet density
(D) Dry density
Choose the most appropriate sequence in the decreasing order of magnitude of the densities of a soil sample:

• A. (C), (B), (A), (D)
• B. (A), (B), (C), (D)
• C. (A), (C), (B), (D)
• D. (A), (B), (C), (D)

Hint:

Wet density>Submerged density>Saturated density>Dry density.

Answer 1

The Correct Option is A

Step 1: Understanding the Densities.
- Wet density is the highest because it includes the total mass of soil and water.
- Submerged density is lower than the wet density but higher than the saturated density.
- Saturated density includes both the dry soil mass and water content.
- Dry density is the lowest because it only considers the soil solids and excludes the water content.

Step 2: Conclusion.
Thus, the correct order from highest to lowest is: Wet density (C), Submerged density (B), Saturated density (A), Dry density (D), making option (1) the correct answer.

Final Answer: \[ \boxed{1. \, (C), (B), (A), (D)} \]
