QUICKSAND IS AGITATED SATURATED LOOSE SAND
Quicksand is a colloid hydrogel consisting of fine granular material (such as sand, silt or clay), and water.
Quicksand forms in saturated loose sand when the sand is suddenly agitated. When water in the sand
cannot escape, it creates a liquefied soil that loses strength and cannot support weight. Quicksand can
form in standing water or in upwards flowing water (as from an artesian spring). In the case of upwards
flowing water, seepage forces oppose the force of gravity and suspend the soil particles.
The saturated sediment may appear quite solid until a sudden change in pressure or shock initiates
liquefaction. This causes the sand to form a suspension and lose strength. The cushioning of water gives
quicksand, and other liquefied sediments, a spongy, fluidlike texture. Objects in liquefied sand sink to the
level at which the weight of the object is equal to the weight of the displaced soil/water mix and the
submerged object floats due to its buoyancy.
