Quicksand Phenomenon

Sand or sand suction vacuum is kaloid hydrogel consisting of sand , water and clay . Quicksand usually found around water sources such as at the beach , river and swamp . Quicksand has a density of 2 grams / milliliter while the human density is 1gram/mililiter this causes the human body that goes down to the sands of life shall not die unless it goes down head first because people will be in waist deep suction or half of the body posture .

When stuck in quicksand , the more we struggled to get out of it , the faster we will sink . If we just relax , our body will float in it because your body has a smaller density than the quicksand .

Quicksand is not a unique soil type , usually it is just ordinary sand or other types of rough ground . Quicksand is nothing more than a mixture of concentrated between sand and water . It can happen anywhere under the right conditions by Denise Dumouchelle , geologists from the United States Geological Survey ( USGS ) .

Quicksand occurs when water seeps into the area of ​​loose sand and sand then becomes easy to move . If water is trapped in a collection of sand and could not get out , then formed " liquid soil " that can no longer hold our weight . There are two ways in which the sand could be a " quicksand " :

1 . Groundwater flow - the flow of water to the power of the opposing forces of gravity , causing the sand grains become lighter . 2 . Earthquakes - Power ground shaking can increase the pressure of shallow groundwater , which melt layer of sand and mud . Liquid surface will lose strength , causing buildings or other objects on its surface would sink or fall . Vibration coupled water flow reduces the friction between sand particles and causes the sand to behave like a liquid . To understand the quicksand , we must understand the process of liquefaction . When the soil melts , like quicksand , it will lose strength and behave like a viscous liquid . Liquefaction can cause drowning building during an earthquake . Quicksand can occur in almost any location where there is a stream of water . The place where quicksand most likely to occur include : river beach Near the lake shore Near the underground springs swamp When you're at the beach , notice the difference in the sand as you stand on a different part of the beach that have different levels of humidity . If you stand in the driest part of the beach , the sand holding and you will be fine . Friction between sand particles create a stable surface to stand on it .

Subhanallah, Quran Miracles That About the River in Seabed

وَهُوَ الَّذِي مَرَجَ الْبَحْرَيْنِ هَذَا عَذْبٌ فُرَاتٌ وَهَذَا مِلْحٌ أُجَاجٌ وَجَعَلَ بَيْنَهُمُا بَرْزَخًا وَحِجْرًا مَّحْجُورًا “Dan Dialah yang membiarkan dua laut mengalir (berdampingan) ; yang ini tawar lagi segar dan yang lain masin lagi pahit; dan Dia jadikan antara keduanya dinding dan batas yang menghalangi.” (Q.S Al Furqan:53) If you are a person who likes to watch TV design `Discovery 'must know Mr.Jacques Yves Costeau, he was an expert scuba oceanografer and leading experts from France. White-haired old man who throughout his life perbagai dive into the ocean floor around the world and made ​​a documentary movie about the natural beauty of the sea floor to be watched all over the world. One day while exploring under the sea, he suddenly encountered a set of fresh eyes fresh water-a very unpleasant taste mingled kerana not / do not merge with the salty sea water around him, as if there are no walls or membranes that limit both.

Mr bizarre phenomenon dizzy. Costeau and encouraged him to seek the cause of the separation of fresh water from salt water in the middle of the ocean. He began to think, lest it just halusinansi or khalayan while diving. The time had passed after the incident, but he never get a satisfactory retort about the odd phenomenon. Until one day he met a Muslim professor, then he tells the strange phenomenon. The professor thought of the Quran about the meeting of two oceans (Surat ar-Rahman verses 19-20) is often identified with the Suez Canal. The verse reads مَرَجَ الْبَحْرَيْنِ يَلْتَقِيَانِ {19} بَيْنَهُمَا بَرْزَخٌ لاَّيَبْغِيَانِ {20} Artinya: “Dia biarkan dua lautan bertemu, di antara keduanya ada batas yang tidak boleh ditembus”. Kemudian dibacakan surat Al Furqan ayat 53 di atas. In addition, in some books commentary, verse about the meeting of two seas but no water is defined as the location mixed estuaries, where a meeting was held between fresh water from rivers and salt water from the sea. But that interpretation does not explain the following verse of Surat ar-Rahman verse 22 which reads يَخْرُجُ مِنْهُمَآ اللُّؤْلُؤُ وَالْمَرْجَانِ {22} Artinya: “Keluar dari keduanya mutiara dan marjan”. Padahal di muara sungai tidak ditemukan mutiara. Mr.Costeau fascinated to hear the verses of the Qur'an that, beyond admiration to see the wonders of sight he had ever seen in the deep ocean. Qur'an is impossible compiled by Muhammad who lived in the seventh century, an era when there is no sophisticated diving equipment to reach the far flung locations in the depths of the ocean. Truly a miracle, the news of the odd phenomenon 14 centuries ago Finally proved in the 20th century. Mr. Costeau also said that the Qur'an is the holy book that contains the actual word of God, that all abortion is absolutely true. He immediately embraced Islam.
