Really? edit
The introductory section contains this paragraph:
"Dilatancy is a common feature of soils and sands. Its effect can be seen when the wet sand around the foot of a person walking on beach appears to dry up. The deformation caused by the foot expands the sand under it and the water in the sand moves to fill the new space between the grains."
This sounds very questionable. Some explanation is need to clarify how the pressure of a foot on sand causes the sand to "expand under it".
In what sense does the sand "expand"?50.234.60.130 (talk) 11:56, 20 December 2020 (UTC)
