A group of hikers encountering quicksand on the banks of the Paria River, Utah Quicksand warning sign near Lower King Bridge, Western Australia. Quicksand is a shear thinning non-Newtonian fluid: when undisturbed, it often appears to be solid ("gel" form), but a less than 1% change in the stress on the quicksand will cause a sudden decrease in its viscosity ("sol" form).
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. Dry quicksand can also be a resulting phenomenon of contractive dilatancy.
People and cars can also become stuck in mud, as in quicksand. Heavy rainfall, snowmelt, or high levels of groundwater may trigger a movement of soil or sediments, possibly causing mudslides, landslides, avalanches, or sinkholes. Mudslides in volcanic terrain (called lahars) occur after eruptions as rain remobilizes loose ash deposits. [8]
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.
Construction on bay mud sites is difficult because of the soil's low strength and high compressibility. Very lightweight buildings can be constructed on bay mud sites if there is a thick enough layer of non-bay-mud soil above the bay mud, but buildings which impose significant loads must be supported on deep foundations bearing on stiffer ...
Have found loads of shelf-stable almond milk, cereal, cheese, yogurt, pre-made meals, snacks, chips, etc. Just use common sense. If it looks, smells, or tastes off don’t risk it.
