As soil mechanics definition

Compression:-process  of applying load to the soil

 Consolidation:- is the process in which reduction in volume takes place by expulsion of water under long term static loads

Shrinkage:-is decreasing in soil volume due to moisture decreasing by evaporation from the soil surface in dry climates, lowering of the groundwater table or desiccation of soil by trees during temporary dry spells in otherwise humid climates

Compaction:-is process to densification soil mechanically

 Rebound:-is phenomena that shown on surface of the soil lay when remove stress from it  the lay will return back to same thickness after removing the load

 

 Expansion:-is increase in soil volume when water content increase

Swelling:-is increase in the volume due to increase of the soil particles by water absorption i.e when particle absorbed moisture the size will increase                      

__( Loosening or scarifying:- To break up the surface of (topsoil or pavement

Compression:The loss in external volume under constant load

 

Consolidation:The loss in volume with time

 

Shrinkage:The loss in volume resulting from capillary stresses during drying soil

 

Compaction:The loss in volume due to artificial temporary load as rolling, tamping, vibration

 

Rebound:The increase in volume due to remove sustained load

 

Expansion:The increase in volume with time

 

Swelling:The increase in volume resulting from increasing of water content

 

Loosening or scarifying:The increase in volume due to artificial operation
