16.8 Summary
1. The state of a soil in the ground is determined primarily by the history of deposition
and erosion, but it may be altered subsequently by the various processes of ageing.
2. The principal processes of ageing are creep, cementing, weathering and changes
in the salinity of the pore water.
3. Ageing may change either the current state or the position of the state boundary
surface.
