In general we understand the meaning of Squash - when the sand, mud or gravel comes in contact with the flow of the impoverished river, the friction that is in the sand or the grains of sand is reduced, and it can not bear the burden of sand or soil - it is called Squash. Water is not only on the soil but also below the soil. This phenomenon occurs in two ways naturally occurring underground water. 1- Flowing underground water / spring 2- Earthquake. This sticking water moistens the soil around it. To be liquefied this way, at one stage the friction between the sand molecules decreases and the sand behaves like water molecules. The wet sand is in a stage that it cannot make the pressure of any heavy object. In some water the water in the solid water sinks along with it and drops it slowly after wearing something in the jam. Basically this is a scientific explanation. We see this kind of thing on the beach. If anyone is standing in the sandstorm, then it can be seen after a while that his legs are slowly sitting inside the sand. It's also a kind of small snack. However, the depth of this type of squash is only a few inches. So just place our feet on those places. But the places where it is more in depth, are very dangerous. Such a hole is coupled with a lot of water and liquid mud. There is no escape if it gets trapped once. To sink slowly down the sidewalk. As much as the movement of the body becomes drowning, the body usually in the river or sea shore, the mud is hidden inside the mixed sand, while the Squash is hidden. If a person approaches the hole, then the body of the sand continues to move away. As a result, people cannot come up and try on top. If you try to get out of there after squabbling, then you have to drown more quickly in body pressure. Those who do not come forward in time, they are sure to die in death. However, most of the thieves are not usually deadly. But it is a strange wonder of nature. The places where there is more water, there are more chances of Squash. Such as water, river, canal, seashore and wetland. Places where there is underground water flow can be possessed or possessed. If you get stuck in the squash, then there will be no impatience. If you are impatient and hand-footed, then you are more likely to get stuck. Everyone should keep in mind that Squash is a lot more dense than water. So much easier than drinking water in squirrel. If there is a heavy object with it, you have to leave it. Because heavy objects can drag down more quickly. The density of the human body is 62.4 pounds per cubic feet. The density of squash is more than water. That is, if people can stay in the water, then they will be able to do so in Squash, because the density of the squash is more than water. So if you fall into squash, then you cannot move fast. The fear of drowning will increase as the movement will increase.
