What is quicksand?

Quicksand is a peculiar creation of nature. Though it has an ordinary appearance, yet it is very dangerous. From a distance, you cannot distinguish between ordinary soil and quicksand. By mistake, however, if some body enters quicksand, he will slowly go down and finally sink in it.
Once you are trapped in quicksand, it is very difficult to get out of it. Quicksand can devour anything big or small. Do you know what quicksand is, how it is formed and how to save oneself if trapped in it?
Broadly speaking, quicksand is a type of slush, but its depth is much more. Quicksands are normally formed on such river banks and sea shores where the earth's crust contains layers of clay with huge quantities of sand above. Water waves deposit water into this mixture of clay and sand. The inner layers of the clay prevent the water from draining away. Slowly and slowly this stagnated water starts rotting and converts the entire soil into deep slush. It becomes pasty. It is how quicksand is formed.
Quicksand contains more of water than soil. Hence people can swim in it. But it is dangerous to swiftly move hands and legs the moment you are trapped in it. On the contrary you should make slow movements and allow water to accumulate around you. You will find it easier to swim in this accumulated water and come alive to the solid ground on the bank. This way you can save yourself from quicksand.
