Lesson one hundred thirty nine :Mystery of mountains !

Imam Ali( A. S. )says:

وَ وَتَّدَ بِالصُّخُورِ مَيَدانَ ارْضِهِ‌

Translation

Shaking and movement of the earth is prevented by mountains..

Brief description

Nowadays, it has been confirmed that as gravity of moon is effective in the flux and reflux of seas and tides up their water twice a day, with difference of one meter and more and even 51 meters in some parts, it is also effective on the solid crust of earth and lifts it up for 03 centimeter and then lifts it down. But solidity of earth crust due to existence of mountains, the roots of which are connected to each other and have created a mail network round the earth prevents its more effect.

In fact, if there were not mountains and earth crust was not solid, and they were always in flux and reflux, was there any peace for us? Islamic leaders have mentioned this reality 41 centuries ago.
