11. Hydrology : THE WATER CYCLE In 1580, Bernard Palissy was the first person to describe the present day concept of ‘water cycle’. He described how water evaporates from the oceans and cools to form clouds. The clouds move inland where they rise, condense and fall as rain. This water gathers as lakes and streams and flows back to the ocean in a continuous cycle. In the 7th century B.C., Thales of Miletus believed that surface spray of the oceans was picked up by the wind and carried inland to fall as rain. In earlier times people did not know the source of underground water. They thought the water of the oceans, under the effect of winds, was thrust towards the interior of the continents. They also believed that the water returned by a secret passage or the Great Abyss. This passage is connected to the oceans and has been called the ‘Tartarus’, since Plato’s time. Even Descartes, a great thinker of the eighteenth century, subscribed to this view. Till the nineteenth century, Aristotle’s theory was still prevalent. According to this theory, water was condensed in cool mountain caverns and formed underground lakes that fed springs. Today, we have come to know that the rainwater that seeps into the cracks of the ground is responsible for this. This is described by the Quran in the following verses: “Seest thou not that Allah sends down rain from the sky, and leads it through springs in the earth? then He causes to grow, therewith, produce of various colours.” Quran (39:21) “He sends down rain from the sky and with it gives life to the earth after it is dead: Verily in that are Signs for those who are wise.” Quran (30:24) “And We send down water from the sky according to (due) measure, and We cause it to soak in the soil; and We certainly are able to drain it off (with ease).” Quran (23:18) No other text dating back 1400 years ago gives such an accurate description of the water cycle. EVAPORATION “By the Firmament which returns (in its round),” Quran (86:11) WINDS IMPREGNATE CLOUDS “And We send the fecundating winds, then cause the rain to descend from the sky, therewith providing you with water (in abundance).” Quran (15:22) The Arabic word used here is "lawaaqih" which is the plural of "laqih" from "laqaha", which means to impregnate or fecundate. In this context, impregnate means that the wind pushes the clouds together increasing the condensation that causes lightning and thus rain. A similar description is found in the following verses of the Quran: “Seest thou not that Allah makes the clouds move gently, then joins them together, then makes them into a heap?–then wilt thou see rain issue forth from their midst. And He sends down from the sky mountain masses (of clouds) wherein is hail: He strikes therewith whom He pleases and He turns it away from whom He pleases. the vivid flash of His lightning well-nigh blinds the sight.” Quran (24:43) “It is Allah Who sends the Winds, and they raise the Clouds: then does He spread them in the sky as He wills, and break them into fragments, until thou seest raindrops issue from the midst thereof: then when He has made them reach such of His servants as He wills, behold, they do rejoice!” Quran (30:48) Modern data on Hydrology agrees perfectly with the Quranic description on the same subject. The water cycle is described in several other verses of the Glorious Quran, including 7:57, 13:17, 25:48-49, 35:9, 36:34, 45:5, 50:9-11, 56:68-70 and 67:30. 12. Geology: Mountains are like tent pegs Praise be to Allaah, we seek His help and His forgiveness. We seek refuge with Allaah from the evil of our own souls and from our bad deeds. Whomsoever Allaah guides will never be led astray, and whomsoever Allaah leaves astray, no one can guide. I bear witness that there is no god but Allaah, and I bear witness that Muhammad is His slave and Messenger. Bismillah Walhamdulillah Was Salaatu Was Salaam 'ala Rasulillah As-Salaam Alaikum Wa-Rahmatullahi Wa-Barakatuhu Miracles of Quraan (part 3) BARRIER BETWEEN SWEET AND SALT WATERS “He has let free the two bodies of flowing water, meeting together: Between them is a Barrier which they do not transgress.” [Quran 55:19-20] In the Arabic text the word "barzakh" means a barrier or a partition. This barrier, however, is not a physical partition. The Arabic word maraja literally means ‘they both meet and mix with each other’. Early commentators of the Quran were unable to explain the two opposite meanings for the two bodies of water, i.e. they meet and mix, and at the same time there is a barrier between them. Modern Science has discovered that in the places where two different seas meet, there is a barrier between them. This barrier divides the two seas so that each sea has its own temperature, salinity and density. Oceanologists are now in a better position to explain this verse. There is a slanted unseen water barrier between the two seas through which water from one sea passes to the other. But when the water from one sea enters the other sea, it loses its distinctive characteristic and becomes homogenized with the other water. In a way this barrier serves as a transitional homogenizing area for the two waters. This phenomenon is also mentioned in the following verse of the Quran: “And made a separating bar between the two bodies of flowing water?” Quran (27:61) This phenomenon occurs in several places, including the divider between the Mediterranean and the Atlantic Ocean at Gibralter. A white bar can also be clearly seen at Cape Point, Cape Peninsula , South Africa where the Atlantic Ocean meets the Indian Ocean . But when the Quran speaks about the divider between fresh and salt water, it mentions the existence of “a forbidding partition” with the barrier. “It is He Who has let free the two bodies of flowing water: one palatable and sweet, and the other salty and bitter; yet has He made a barrier between them, and a partition that is forbidden to be passed. (Quran 25:53) Modern science has discovered that in estuaries, where fresh (sweet) and salt water meet, the situation is somewhat different from that found in places where two salt water seas meet. It has been discovered that what distinguishes fresh water from salt water in estuaries is a “pycnocline zone with a marked density discontinuity separating the two layers.” This partition (zone of separation) has a salinity different from both the fresh water and the salt water. This phenomenon occurs in several places, including Egypt , where the river Nile flows into the Mediterranean Sea . These scientific phenomena mentioned in the Quran was also confirmed by Dr. William Hay, a wellknown marine scientist and Professor of Geological Sciences at the University of Colorado , U.S.A. 15. Darkness in The Depth of Oceans Professor. Durga Rao is a world renowned expert in the field of Marine Geology and was a professor at King Abdul Aziz University in Jeddah. He was asked to comment on the following verse: “Or (the Unbelievers’ state) is like the depths of darkness in a vast deep ocean, overwhelmed with billow topped by billow, topped by (dark) clouds: depths of darkness, one above another: if a man stretches out his hand, he can hardly see it! For any to whom Allah giveth not light, there is no light!” Quran (24:40) Prof. Rao said that scientists have only now been able to confirm, with the help of modern equipment, that there is darkness in the depths of the ocean. Humans are unable to dive unaided underwater for more than 20 to 30 metres, and cannot survive in the deep oceanic regions at a depth of more than 200 metres. This verse does not refer to all seas because not every sea can be described as having accumulated darkness layered one over another. It refers especially to a deep sea or deep ocean, as the Qur’an says, “darkness in a vast deep ocean”. This layered darkness in a deep ocean is the result of two causes: 1. A light ray is composed of seven colours seen in the rainbow. These seven colours are Violet, Indigo, Blue, Green, Yellow, Orange and Red (VIBGYOR). The light ray undergoes refraction when it hits water. The upper 10 to 15 metres of water absorb the red colour. Therefore, if a diver is 25 metres under water and gets wounded, he would not be able to see the red colour of his blood, because the red colour does not reach this depth. Similarly, orange rays are absorbed at 30 to 50 metres, yellow at 50 to 100 metres, green at 100 to 200 metres, and finally, blue beyond 200 metres and violet and indigo above 200 metres. Due to successive disappearance of colour, one layer after another, the ocean progressively becomes darker, i.e. darkness takes place in layers of light. Below a depth of 1000 meters there is complete darkness. 2. The suns rays are absorbed by clouds which in turn scatter light rays thus causing a layer of darkness under the clouds. This is the first layer of darkness. When light rays reach the surface of the ocean they are reflected by the wave surface giving it a shiny appearance. Therefore, it is the waves which reflect light and cause darkness. The unreflected light penetrates into the depths of the ocean. Thus, the ocean has two parts. The surface characterized by light and warmth and the depth characterized by darkness. The surface is further separated from the deep part of the ocean by waves. The internal waves cover the deep waters of seas and oceans because the deep waters have a higher density than the waters above them. The darkness begins below the internal waves. Even the fish in the depths of the ocean cannot see; their only source of light is from their own bodies. The Quran describes this aptly: “Darkness in a vast deep ocean overwhelmed with waves topped by waves”. In other words, above these waves there are more types of waves, i.e. those found on the surface of the ocean. The Quranic verse continues, “topped by (dark) clouds; depths of darkness, one above another.” These clouds as explained are barriers one over the other that further cause darkness by absorption of colours at different levels. Prof. Durga Rao concluded by saying, “1400 years ago a normal human being could not explain this phenomenon in so much detail. Thus the information must have come from a supernatural source”.

Join Today and learn more about Islam , Insha'Allah In geology, the phenomenon of ‘folding’, is a recently discovered fact. Folding is responsible for the formation of mountain ranges. The earths crust, on which we live, is like a solid shell, while the deeper layers are hot and fluid, and thus inhospitable to any form of life. It is also known that the stability of the mountains is linked to the phenomenon of folding, for it was the folds that were to provide foundations for the reliefs that constitute the mountains. Geologists tell us that the radius of the Earth is about 6,035 km and the crust on which we live is very thin, ranging between 2 to 35 km. Since the crust is thin, it has a high possibility of shaking. Mountains act like stakes or tent pegs that hold the earths crust and give it stability. The Quran contains exactly such a description: “Have We not made the earth as a wide expanse, and the mountains as pegs?” Quran (78:6-7) The Arabic word "awtaad" means stakes or pegs (like those used to anchor a tent); they are the deep foundations of geological folds. A book entitled ‘Earth’ is regarded as a basic reference textbook on geology in many universities around the world. One of the authors of this book is Dr. Frank Press, who was the President of the Academy of Sciences in the USA for 12 years and was the Science Advisor to former US President Jimmy Carter. In this book, he illustrates the mountain in a wedge-shape and the mountain itself as a small part of the whole, whose root is deeply entrenched in the ground.1 According to Dr. Press, the mountains play an important role in stabilizing the crust of the earth. The Quran clearly mentions the function of the mountains in preventing the earth from shaking: “And We have set on the earth mountains standing firm, lest it should shake with them.” Quran (21:31) Similar said in Quran (31:10) and (16:15) The Quranic descriptions are in perfect agreement with modern geological data. 13. Geology: Mountains firmly fixed The surface of the earth is broken into many rigid plates that are about 100 km in thickness. These plates float on a partially molten region called aesthenosphere. Mountain formations occur at the boundary of the plates. The earths crust is 5 km thick below oceans, about 35 km thick below flat continental surfaces and almost 80 km thick below great mountain ranges. These are the strong foundations on which mountains stand. The Quran refers to the strong mountain foundations in the following verse: “And the mountains hath He firmly fixed.” Quran (79:32) A similar message is contained in the Quran in 88:19. Thus, the information contained in the Glorious Quran about the nature of mountains, is in perfect agreement with recent discoveries in geology. 14.
