The document discusses the formation of mountains and how they stabilize the Earth's crust according to both the Quran and modern science. It notes that mountains form through accumulation of material from the bottom up, like throwing dust to form a hill. Mountains function like pegs to balance the Earth and without mountain chains, the Earth would not be stable, as seen in a NASA image. The Quran mentioned over 14 centuries ago how mountains fix the Earth and form, showing no contradiction between the Quran and modern geological science.
