1400 years ago people thought that mountains lie on-top of the surface. Nobody knew that there were mountains below the surface. Today geologists discovered mountains 400 km beneath the surface, with peaks 40 km high.
Deep inside Earth, scientists find weird blobs and mountains taller than Mount Everest
Researchers such as Barbara Romanowicz at the University of California, Berkeley are using seismic (earthquake) waves to scan our planet’s innards, much like doctors use ultrasound to peer inside patients. What they’re seeing is full of complex detail — not a bland mineral hunk, but a rich and dynamic inner landscape.
The mantle appears to be layered like an onion, with major transitions 250 miles and 410 miles down. At the 410-mile level, researchers recently identified a tremendous interior mountain range, with peaks perhaps even taller than Mount Everest. “Recently, we’ve discovered another change at about 1,000 kilometers [600 miles] depth,” Romanowicz says.
400 km beneath the surface Earth has mountains 40 km high that slow the motion of the ductile layer above it. This was only known recently, however this was portrayed in the Quran 1400 years before it was discovered.
And We placed in earth mountains, lest it sways with them, and We placed therein signposts and passages, that they may be guided.
٣١ وَجَعَلْنَا فِي الْأَرْضِ رَوَاسِيَ أَنْ تَمِيدَ بِهِمْ وَجَعَلْنَا فِيهَا فِجَاجًا سُبُلًا لَعَلَّهُمْ يَهْتَدُونَ
"Fee فِي" means inside. ("Aala على" means on-top; however it wasn't used here.) The Quran specifically says that Earth has mountains inside it so that it doesn't sway. Today we know that 400 km beneath the surface Earth has mountains 40 km high that slow the motion of the ductile layer above it.
