3)THE EARTH DISGORGES ITS CHARGES
When the earth is convulsed with its quaking and the earth then disgorges its charges and man asks, "What is wrong with it?", on that Day it will impart all its news. (Qur'an, 99:1-4)
The word "zilzal" in Arabic means earthquake, or tremors, and the word "athqalaha" means "charges, heavy burdens." When one considers the above verses in the light of the first meaning, it can be seen that reference is being made to an important scientific fact about earthquakes.
Surat az-Zilzal 2 mentions the earth disgorging its charges. Indeed, as a result of research in recent years, it has been realised that there are heavy metals at the centre of the Earth, and that these appear as a result of movements on the Earth's surface. According to geologists' calculations, as the Earth cooled, heavy and dense substances sank to its centre, while lighter ones rose to the surface. For that reason, the Earth's crust consists of the least heaviest substances (basalt and granite rocks), while heavy metals (nickel and iron) are found in the core. As a result, the subsurface, which consists of molten metals, is made of a material that is much heavier and denser than the surface.
During earthquakes, the heavy substances below the surface have an opportunity to rise, and the Earth thus disgorges its charges, as revealed in the Qur'an. Moreover, those regions where metal reserves are most concentrated are also those with the greatest volcanic activity. These scientific findings, which emerged only recently, and as a result of wide-ranging research, are just some of the scientific facts indicated by Allah in the Qur'an.
4)THE MOVEMENT OF MOUNTAINS
In one verse, we are informed that mountains are not motionless as they seem, but are in constant motion.
And you see the mountains, you think they are solid, while they are passing by like the clouds. The making of God who perfected everything. He is Expert over what you do. (Qur'an, 27:88)
This motion of mountains is caused by the movement of the Earth's crust that they are located on. The Earth's crust "floats" over the mantle layer, which is denser. It was at the beginning of the 20th century when, for the first time in history, a German scientist by the name of Alfred Wegener proposed that the continents of the Earth had been attached together when it first formed, but then drifted in different directions, and thus separated as they moved away from each other.
Geologists understood that Wegener was right only in the 1980s, 50 years after his death. As Wegener pointed out in an article published in 1915, the land masses on the Earth were joined together about 500 million years ago, and this large mass, called Pangaea, was located in the South Pole.
Approximately 180 million years ago, Pangaea divided into two parts, which drifted in different directions. One of these giant continents was Gondwana, which included Africa, Australia, Antarctica and India. The second one was Laurasia, which included Europe, North America and Asia, except for India. Over the next 150 million years following this separation, Gondwana and Laurasia divided into smaller parts.
These continents, that emerged after the split of Pangaea, have been constantly moving on the Earth's surface at a rate of several centimetres per year, and in the meantime changing the sea to land ratios of the Earth.
Discovered as a result of the geological research carried out at the beginning of the 20th century, this movement of the Earth's crust is explained by scientists as follows:
The crust and the uppermost part of the mantle, with a thickness of about 100 kms., are divided into segments called plates. There are six major plates, and several small ones. According to the theory called plate tectonics, these plates move about on Earth, carrying continents and ocean floor with them. Continental motion has been measured at from 1-5 cm per year. As the plates continue to move about, this will produce a slow change in Earth's geography. Each year, for instance, the Atlantic Ocean becomes slightly wider.29
There is an important point that needs to be stated here: Allah referred to the motion of mountains as drifting in a verse of the Qur'an. Today, modern scientists also use the term "continental drift" for this motion.30
Continental drift is something that could not have been observed at the time of the revelation of the Qur'an, though Allah clearly indicated how it was to be understood: "You see the mountains you reckoned to be solid" in the verse. Though, He further described this action in the following verse, stating that the mountains were going past like clouds. As has been indicated, attention is clearly drawn to the movement of the layer in which the mountains are fixed.
its only recently discovered by science, should have been revealed in the 7th century, when conceptions of the nature of the universe were based on superstition and myth. This is another very important proof that the Qur'an is the word of Allah.
5)THE MIRACLE OF IRON Iron is one of the elements highlighted in the Qur'an. In Surat al-Hadid, meaning Iron, we are informed:
And We also sent down iron in which there lies great force and which has many uses for mankind… (Qur'an, 57:25)
The word "
anzalna," translated as "sent down" and used for iron in the verse, could be thought of having a metaphorical meaning to explain that iron has been given to benefit people. But, when we take into consideration the literal meaning of the word, which is, "being physically sent down from the sky," as in the case of rain and Sun rays, we realize that this verse implies a very significant scientific miracle. Because, modern astronomical findings have disclosed that the iron found in our world has come from giant stars in outer space.
38 Not only the iron on earth, but also the iron in the entire Solar System, comes from outer space, since the temperature in the Sun is inadequate for the formation of iron. The sun has a surface temperature of 6,000 degrees Celsius, and a core temperature of approximately 20 million degrees. Iron can only be produced in much larger stars than the Sun, where the temperature reaches a few hundred million degrees. When the amount of iron exceeds a certain level in a star, the star can no longer accommodate it, and it eventually explodes in what is called a "nova" or a "supernova." These explosions make it possible for iron to be given off into space.
39
One scientific source provides the following information on this subject:
There is also evidence for older supernova events: Enhanced levels of iron-60 in deep-sea sediments have been interpreted as indications that a supernova explosion occurred within 90 light-years of the sun about 5 million years ago. Iron-60 is a radioactive isotope of iron, formed in supernova explosions, which decays with a half life of 1.5 million years.
An enhanced presence of this isotope in a geologic layer indicates the recent nucleosynthesis of elements nearby in space and their subsequent transport to the earth (perhaps as part of dust grains)
6)THE SPLITTING EARTH [I swear] by Heaven which returns and the earth which splits. (Qur'an, 86:11-12)
The Arabic word "sadA" in the above verse means "cracking, splitting apart." Allah's swearing by the splitting of the Earth points to an important phenomenon, as do the other scientific miracles in the Qur'an. Scientists first descended to the depths of the seas and oceans in order to study mineral resources in 1945-1946. One of the most important facts to emerge from that research was the fissured structure of the Earth. The rock layer on the external surface of the Earth was split by large numbers of cracks (faults), tens of thousands of kilometres long, running from north to south and east to west. Scientists also realised that there was molten magma under the sea, at depths of 100-150 km.
