Unlike gravel and sand, whose particles are roughly the same size in all three directions (i.e., equidimensional), clay particles are flat (plate- like or flakes). This particle shape makes clay an unstable soil that swells with the addition of water and shrinks when dry. Explain the cause of this phenomenon.
