Mountains Firmly Fixed

The surface of the earth is broken into many rigid plates that are about 100km in thickness. These plates float on a partially molten region called aesthenosphere. Mountain formations occur at the boundary of the plates. The earth’s crust is 5km thick below oceans, about 35km thick below flat continental surfaces and almost 80km thick below great mountain ranges. These are the strong foundations on which mountains stand. The Qur’an also speaks about the strong mountain foundations in the following verse: “And the mountains Hath He firmly fixed.” [Al-Qur’an 79:32] [A similar message is contained in the Qur’an in 88:19, 31:10 and 16:15]
