12 Scientific Facts in The Quran Discovered Centuries Later: Part 2

In the first part of this article on the scientific facts in the Quran, some astronomical facts mentioned were discussed. Here, we review some interesting facts about nature, including some points about mountains, the origin of life, the position of the sky and the seas merging together. 


5. Mountains with Deep Roots under the Ground


the quran


The Quran has used the word stakes to describe mountains: “It is He who has spread out the earth and set in it firm mountains” (13:3), “Did We not make the earth a resting place? and the mountains stakes?” (78:6-7). It means that mountains have deep roots under the ground surface. Mountains do have deep roots, and the word stakes is an accurate description for them. This fact was discovered only in the latter half of the 19th century. The presence of the mountains on the ground also helps to stabilize the crust of the earth [4]. They also hinder the earth-shaking. “He cast in the earth firm mountains lest it should shake with you” (16:15). This is known today under the theory of plate tectonics since the late 1960s [1].

6. The Origin of Life according to the Quran 


the quran 

Life of a human being starts in water. From conception to birth, a fetus is protected and cushioned in a sack of water. A human body needs water in all its cells, organs, and tissues to help regulate its temperature and maintain other bodily functions. Plants also need enough hydration to perform photosynthesis, while animals consume water to carry out cell activity. Overall, water is an essential element for all living beings on earth. This fact was discovered only after the invention of the microscope. Now we know that all living things are made up of cells which are mostly made up of water. This fact has already been stated in the Quran: “We made every living thing out of water? Will they not then have faith?” (21:30).

7. The Sky as the Protector of the Earth

the quran

The sky plays several essential roles as the protector of the earth, such as filtering out the lethal rays of the sun. If there were no sky, the sun’s radiations would have killed off all life on earth. The sky also acts as a blanket around the earth, which protects the living things from freezing out by the cold just above the sky that is approximately -270°C. The greenhouse effect is another role that the sky plays. By warming the surface of the earth by means of heat retention, the sky reduces temperature extremes between day and night [2]. These protective roles of the sky were discovered by scientists in the 20th century. The Quran has mentioned this role of the sky as: “We made the sky a preserved roof and yet they are disregardful of its signs.” (21:32).

8. Where the Seas Meet

the quran

It has been discovered by the scientists that there is a barrier between the two different seas that meet. Hence, each of the seas has its own temperature, salinity, and density, like the Mediterranean Sea and Atlantic Ocean water. Despite large waves, strong currents, and tides in these seas, they neither mix nor do they transgress this barrier [3]. This phenomenon has been mentioned in the Quran as: “He merged the two seas, meeting each other. There is a barrier between them which they do not overstep.” (55:19-20). There is also a case where fresh (sweet) and saltwater meet. Here, the Quran talks about the existence of a forbidding partition along with the barrier: “It is He who merged the two seas: this one sweet and agreeable, and that one briny and bitter, and between the two He set a barrier and a forbidding hindrance.” (25:53). Modern science has discovered that in estuaries, where fresh and saltwater meet, there is a marked density discontinuity that separates the two layers. The salinity of this zone of separation (partition) is different from that of freshwater and that of saltwater. There is, therefore, the division of water in estuaries into three parts: freshwater, saltwater, and the partition [3].
