how does quicksand become quicksand?

Answer 1

Quicksand is not quite the fearsome force of nature that you sometimes see on the big screen. In fact, quicksand is rarely deeper than a few feet. It can occur almost anywhere if the right conditions are present. Quicksand is basically just ordinary sand that has been so saturated with water that the friction between sand particles is reduced. The resulting sand is a mushy mixture of sand and water that can no longer support any weight.

If you step into quicksand, it won't suck you down. However, your movements will cause you to dig yourself deeper into it. In this article, you will learn just how quicksand forms, where it's found and how you can escape its clutches if you find yourself hip-deep in it.

Answer 2

It could be asked, how salt water becomes quicksand - state in which saturated sand loses its supporting capacity and acquires the character of a liquid. Quicksand is usually found in hollows at the mouths of large rivers or along flat stretches of streams or beaches where pools of water become partially filled with sand and an underlying layer of stiff clay or other dense material prevents drainage.

if the water under the sand has salts within it, and can not drain away, then you have this liquid hydrocolloid gel - consisting of fine granular matter (such as sand or silt), clay, and salt water.

When unperturbed, it often appears to be solid; however, even a minor (less than 1%) change in the stress on the quicksand will cause a sudden decrease in its viscosity. After the initial perturbation—such as a person attempting to walk on it—the water and sand in the quicksand separate and dense regions of sand sediment form.

In order to move within the quicksand, a person or object must apply sufficient pressure on the compacted sand to re-introduce enough water to liquefy it. The forces required to do this are quite large: to remove a foot from quicksand at a speed of one centimeter per second would require the same amount of force as "that needed to lift a medium-sized car."

After the initial perturbation—such as a person attempting to walk on it—the water and sand in the quicksand separate and dense regions of sand sediment form; it is because of the formation of these high volume fraction regions that the viscosity of the quicksand seems to suddenly increase.

Answer 4

Quicksand is usually just a body of water that's been covered in sand. The resulting mush is quicksand.

Answer 5

Quicksand is sand that has a lot of water inside it, beneath the surface. It's not wet enough to be mud.

It's a non-newtonian fluid, which means if you walk on it quick it will support you but if you stand still you will slowly sink in it. Eactly the same as custard is.

Answer 6

if there is plenty of water or other lubrication between the sand allowing them to act like a liquid. It's like custard it is a liquid, but try stir it as hard as you can the spoon will lodge and you cant move it can't remember the name of the thing

Answer 7

it does a lot of training

Answer 8

wheels and red bull lol dunno im afraid!
