God has said in the Quran:
“Have We not made the earth as a bed, and the mountains as pegs?” (Quran 78:6-7)
. The Quran says::
“And He has set firm mountains in the earth so that it would not shake with you…” (Quran 16:15)
This was revealed by Quran 1400 years ago. Science confirms it.
The modern theory of plate tectonics holds that mountains work as stabilizers for the earth. This knowledge about the role of mountains as stabilizers for the earth has just begun to be understood in the framework of plate tectonics since the late 1960’s.
Professor Siaveda,is one of the best known marine geologists from Japan. He is also one of the most famous scientists in the world. Replyingto a number of questions in his area of specialization,he said that mountains have roots to support them. Professor Siaveda described the shape of all mountains whether they are on land or in the sea as being in the shape of a wedge.
Could anyone during the time of Prophet Muhammad (sallallahu ‘alaihi wa sallam) have known of the shape of these mountains? Could anyone imagine that the solid massive mountain that he sees before him actually extends deep into the earth and has a root as scientists assure?
In the book named earth by Tarbuck and Lutgens
(* Earth, Press and Siever, p. 435. Also see Earth Science, Tarbuck and Lutgens, p. 157.)
The word awtad means stakes or pegs (like those used to anchor a tent); they are the deep foundations of geological folds.
A book named Earth is considered as a basic reference textbook on geology in many universities around the world. One of the authors of this book is 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. According to Dr. Press, the mountains play an important role in stabilizing the crust of the earth.
