What does sand feel and what it is characteristics?
-Sand feels gritty when rubbed between the fingers.
-Sand is a granular material composed of finely divided rock and mineral particles. Sand has various compositions but is defined by its grain size. Sand grains are smaller than gravel and coarser than silt.
What does clay feel and what is its characteristics?
-Clay feels sticky when wet.
-Clay minerals all have a great affinity for water. Some swell easily and may double in thickness when wet. Most have the ability to soak up ions (electrically charged atoms and molecules) from a solution and release the ions later when conditions change. Water molecules are strongly attracted to clay mineral surfaces.
