"Have We not made the earth as a wide expanse, And the mountains as pegs?" (Quran, 78:6-7) .
The book "Earth" by Professor Emeritus Frank Press , is a basic reference book in many universities . The book says that mountains have underlying roots. These roots are deeply embedded in the ground, thus, mountains have a shape like a "peg".
Science books have stated this fact as follows:
- "Mountains have deep roots under the surface of the ground". (Earth, Press and Siever, p. 413.)
- "The mountains, like pegs, have deep roots embedded in the ground". (Anatomy of the Earth, Cailleux, p. 220.)
- "The mountains are peg-like in shape, due to their deep roots". (Earth Science, Tarbuck and Lutgens, p. 158.)
Modern science has proven that mountains have deep roots under the surface of the ground . The theory of mountains having deep roots was introduced in the second half of the nineteenth century. Mountain roots are deeper than their part seen above the ground. Since generally larger part of a peg is under the surface, the mountains can be best described by the word "peg". This information exactly matches the statement in the Quran: Allah(God) has said in the Quran: "Have We not made the earth as a wide expanse, And the mountains as pegs?" (Quran, 78:6-7) .
Dr. Press explains that Mountains play an important role in stabilizing the crust of the earth. They interfere with the shaking of the earth. The modern theory of plate tectonics also states that mountains work as stabilizers for the earth.
Actually, the crust of the earth floats on a liquid. The depths of the mountain go as far down as 35 km like pegs driven into the earth. Just like the pegs used to stabilize a tent on the ground. This information exactly matches the statement in the Quran: "And He has set up on the earth mountains standing firm, lest it should shake with you;" (Quran, 16:15)
This is another fact that the Quran revealed 1400 years ago.
