Quicksand can form in standing water or in upward flowing water (as from an artesian spring). In the case of upward-flowing water, forces oppose the force of gravity and suspend the soil particle. The cushioning of water gives quicksand, and other liquefied sediments, a spongy, fluid-like texture.
Quicksand forms when water saturates an area of loose sand, and the sand is agitated. When the water trapped in the batch of sand cannot escape, it creates liquefied soil that can no longer resist force. Quicksand can be formed by standing or (upwards) flowing underground water (as from an underground spring), or by earthquakes.
Dry quicksand is loose sand whose bulk density is reduced by blowing air through it and which yields easily to weight or pressure. It acts similarly to normal quicksand , but it does not contain any water and does not operate on the same principle.
Quicksand is loose, water-logged soil that yields easily to weight or pressure. It can be formed when sand , silt , clay , or other grainy soil is saturated or supersaturated by water flowing from below ground (such as from an underground spring ) with enough pressure to separate and suspend the grains.
A soil scientist examining horizons within a soil profile. Soil science is the study of soil as a natural resource on the surface of the Earth including soil formation, classification and mapping; physical, chemical, biological, and fertility properties of soils; and these properties in relation to the use and management of soils.
It turns out that quicksand, known as supersaturated sand, is a real thing around the world, even in Maine, far from the jungle locations where Hollywood has used it to add drama by ensnaring actors.
