Different minerals have different colors. But it is very rare to see the same mountain streaked with different colors.
This image is in Peru. This was known recently, however this was portrayed in the Quran 1400 years before it was discovered:
٢٧ أَلَمْ تَرَ أَنَّ اللَّهَ أَنْزَلَ مِنَ السَّمَاءِ مَاءً فَأَخْرَجْنَا بِهِ ثَمَرَاتٍ مُخْتَلِفًا أَلْوَانُهَا ۚ وَمِنَ الْجِبَالِ جُدَدٌ بِيضٌ وَحُمْرٌ مُخْتَلِفٌ أَلْوَانُهَا وَغَرَابِيبُ سُودٌ
Today we found such a location, however there is no such thing in the desert of Arabia.
How could an illiterate man who lived 1400 years ago have known about streaked colorful mountains?
The Quran (Koran, the book of Islam) contains scientific knowledge that could not have been known 1400 years ago. It ranges from basic arithmetics to the most advanced topics in astrophysics. You are invited to go through those miracles and judge for yourself.
