What does the term 'consolidation' refer to in soil mechanics?

Step 1: Understand that soil has tiny spaces called pores that can hold water.
Step 2: When weight is applied to the soil (like a building), it pushes down on the soil.
Step 3: This weight causes the water in the soil pores to be pushed out.
Step 4: As the water leaves, the soil particles get closer together, which reduces the volume of the soil.
Step 5: This whole process of water leaving the soil and the soil getting smaller is called consolidation.

Consolidation – The process of reduction in volume of soil due to the expulsion of water from the soil pores under load.
