78:7: And the mountains as pegs?
(88:17-19 : Do they not look at the Camels, how they are made?-
And at the Sky, how it is raised high?-)
And at the Mountains, how they are fixed firm?-
79:32 : And the mountains hath He firmly fixed;-
21:31 : And We have set on the earth mountains standing firm, lest it should shake with them, and We have made therein broad highways (between mountains) for them to pass through: that they may receive Guidance.
Here is what I sent to “Kevin”.The Qur’an always mentions nature as a sign for God’s existence, power and majesty. Every time these are mentioned, they are expressed with a great accuracy, and they also give us information that could have never been known at the time of the Prophet Muhammad. One of these signs includes the function and structure of mountains. The Qur’an mentions that mountains have “peg” like structures and that they have been embedded into earth to stabilise it, a concept known in Geology as isostasy. The Qur’an mentions: “We placed firmly embedded mountains on the earth, so it would not move under them…” and “Have We not made the earth as a bed and the mountains its pegs?” The Qur’an’s eloquent renderings of the facts mentioned above are confirmed by modern science which only came to be understood by the end of the 20th Century. In the book Earth, by Dr. Frank Press, former president of the U.S. National Academy of Sciences, states that mountains are like stakes, and are buried deep under the surface of Earth. With regards to the vital role of mountains, it was formerly understood that mountains were merely protrusions rising above the surface of Earth. However, scientists realised that this was not actually the case, and that the parts known as the mountain roots extended down as far as 10 to 15 times their own height. With these features, mountains play a similar role to a nail or peg firmly holding down a tent, which has been discovered by modern geological and seismic research, a concept known as isostasy. In conclusion, how can we explain this in the light of the fact that this is relatively recent science (with no one at the time of the revelation knowing this information)? What does this tell you about the author? Again, there is no naturalistic explanation.
Just because the mountains are themselves stabilized by isostacy does not mean that the mountains stabilize the earth or the crust by isostacy. Prof David A Young
Isostasy is not a process or a force. It is simply a natural adjustment or balance maintained by blocks of crust of different mass or density [...] Greenland is an example of isostasy in action. The Greenland land mass is mostly below sea level because of the weight of the ice cap that covers the island. If the ice cap melted, the water would run off and raise sea level. The land mass would also begin to rise, with its load removed, but it would rise more slowly than the sea level. Long after the ice melted, the land would eventually rise to a level where its surface is well above sea level; the isostatic balance would be reached again, but in a far different environment than the balance that exists with the ice cap weighing down the land. http://www.enotes.com/earth-science/isostasyThe iREA leaflet you sent said the following: mountains play a similar role to a nail or peg firmly holding down a tent, which has been discovered by modern geological and seismic research, a concept known as isostasy. NO...IT...IS...NOT. That is FACTUALLY INCORRECT
