"have we not made the earth as a wide expanse, and the mountains as pegs?" - the quran

how could anyone have known 1500 years ago that much like an iceberg, mountains may have body mass up to 15 times its height buried into the earth's crust. this plays a significant role to prevent horizontal jerky movement of the lithosperic plates.

modern seismic studies since the 1960s have confirmed this.

something for the thinking mind to ponder about..
