THE FUNCTION OF MOUNTAINS The Qur'an draws attention to a very important geological function of mountains. We placed firmly embedded mountains on the earth, so it would not move under them… (The Qur'an, 21:31) As we have noticed, it is stated in the verse that mountains have the function of preventing shocks in the Earth. This fact was not known by anyone at the time the Qur'an was revealed. It was in fact brought to light only recently as a result of the findings of modern geology. According to these findings, mountains emerge as a result of the movements and collisions of massive plates forming the Earth's crust. When two plates collide, the stronger one slides under the other, the one on the top bends and forms heights and mountains. The layer beneath proceeds under the ground and makes a deep extension downward. That means that mountains have a portion stretching downwards, as large as their visible parts on the Earth. In a scientific text, the structure of mountains is described as follows: Where continents are thicker, as in mountain ranges, the crust sinks deeper into the mantle.4 In a verse, this role of the mountains is pointed out by a comparison with "pegs": Have We not made the earth as a bed and the mountains its pegs? (The Qur'an, 78:6-7) Mountains, in other words, clench the plates in the Earth's crust together by extending above and beneath the Earth's surface at the conjunction points of these plates. In this way, they fix the Earth's crust, and prevent it from drifting over the magma stratum or among its plates. Briefly, we may liken mountains to nails that keep pieces of wood together. This fixing function of the mountains is described in scientific literature by the term "isostasy". Isostasy means the following: Isostasy: general equilibrium in the Earth's crust maintained by a yielding flow of rock material beneath the surface under gravitational stress.5 This vital role of mountains, that was discovered by modern geology and seismic research, was revealed in the Qur'an centuries ago as an example of the supreme wisdom in God's creation. We placed firmly embedded mountains on the earth, so it would not move under them... (The Qur'an, 21:31)

THE MOVEMENT OF MOUNTAINS In one verse, we are informed that mountains are not motionless as they seem, but are in constant motion. You will see the mountains you reckoned to be solid going past like clouds. (The Qur'an, 27:88) This motion of the 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 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. As Wegener pointed out in a 1915 article, the land masses of the earth were joined together some 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 several centimetres per year, in the meantime changing the sea and 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.6

There is a very important point to be stated here: God has referred to the motion of mountains as a drifting action in the verse. Today, modern scientists also use the term "Continental Drift" for this motion. 7 Unquestionably, it is one of the miracles of the Qur'an that this scientific fact, which has recently been discovered by science, was announced in the Qur'an.
