The holy Qur'an directs our attention to the important geological function of mountains.
And We have placed on the earth firm mountains, lest it should shake with them, and We placed therein broad highways for them to pass through, that they may be guided (Quran Sura Al-Anbiya : 31)
As can be seen, it is stated in the verse that mountains work to prevent turbulence in the Earth's surface.
This fact was not known by anyone at the time when the Qur'an was revealed. In fact, they have recently been revealed as a result of discoveries of modern geology.
According to this invention, the mountains appear as a result of the movement and collisions of massive plates forming the earth's crust. When two plates collide, the stronger plates slipped under the other plate, while the one above the fold and form a plateau and mountains. Bottom layer moves under the surface and form a deep extension downward. This means that the mountain has a part that stuck far down that is not less magnitude to that seen in the earth's surface.
In scientific literature, the structure of the mountain is described as follows:
In the thicker parts of the continent, as in mountain ranges, the crust will sink deeper into the layer of magma. (General Science, Carolyn Sheets, Robert Gardner, Samuel F. Howe; Allyn and Bacon Inc.. Newton, Massachusetts, 1985, s. 305)
In a verse, the role of the mountain like this is expressed through a parable as "pegs":
In other words, the mountains hold the plates of the earth's crust extending up and down the earth's surface at points meeting these plates. In this way, they pegged the earth's crust and prevent it from oscillating on a layer of magma or between slab-dial. In short, we can equate the mountain with a nail that makes sheets of wood fixed together.
Erection of the mountain function is described in scientific literature by the term "isostasi". Isostasi meaningful as follows:
Isostasi: equilibrium in the crust is maintained by the flow of rock material beneath the surface pressure due to gravity. (Webster's New Twentieth Century Dictionary, 2. Edition "isostasy", New York, s. 975)
An important role of the mountain which was discovered by modern geology and earthquake research, has been revealed in the Qur'an centuries ago as a proof of wisdom in the creation of God Almighty.
