  B. dry soil

• A. porous soil

  B. unsaturated soil

• A. saturated soil

  B. porous soil

• A. porous soil

  B. dry soil

• A. unsaturated soil

  B. porous soil

Answer explanation

When all of the voids are filled with air, it means that all water has evaporated thus making it a dry soil.

When all the voids are filled with water, it means that all air bubbles in the soil mass has been expelled making the soil mass saturated.

It is the ratio of the weight of the solid soils to the weight of an equal volume of water?

• Density

• Specific Gravity

• Specific Weight

• Molecular Weight

• Volume

It is defined as the moisture content at which soil begins to behave like a liquid material and begins to flow.

It is defined as the moisture content at which soil begins to behave as a plastic material.

• Atterberg Limit

• Liquid Limit

• Plastic Limit

• Shrinkage Limit

• 0.075 mm

It is the settlement of soil in time to time dependent state that results from the expulsion of water from soil pores or voids.

• Compaction

• Consolidation

• Deflection

• Deformation

This property of soil affects the rate of drainage of water throug wells and excavated foundation pits.
