The effect on the balance of Earth's mountains

أَمَّن جَعَلَ ٱلْأَرْضَ قَرَارًۭا وَجَعَلَ خِلَٰلَهَآ أَنْهَٰرًۭا وَجَعَلَ لَهَا رَوَٰسِىَ وَجَعَلَ بَيْنَ ٱلْبَحْرَيْنِ حَاجِزًا ۗ أَءِلَٰهٌۭ مَّعَ ٱللَّهِ ۚ بَلْ أَكْثَرُهُمْ لَا يَعْلَمُونَ

Or, Who has made the earth firm to live in; made rivers in its midst; set thereon mountains immovable; and made a separating bar between the two bodies of flowing water? (can there be another) god besides Allah? Nay, most of them know not.

خَلَقَ ٱلسَّمَٰوَٰتِ بِغَيْرِ عَمَدٍۢ تَرَوْنَهَا ۖ وَأَلْقَىٰ فِى ٱلْأَرْضِ رَوَٰسِىَ أَن تَمِيدَ بِكُمْ وَبَثَّ فِيهَا مِن كُلِّ دَآبَّةٍۢ ۚ وَأَنزَلْنَا مِنَ ٱلسَّمَآءِ مَآءًۭ فَأَنۢبَتْنَا فِيهَا مِن كُلِّ زَوْجٍۢ كَرِيمٍ

He created the heavens without any pillars that ye can see; He set on the earth mountains standing firm, lest it should shake with you; and He scattered through it beasts of all kinds. We send down rain from the sky, and produce on the earth every kind of noble creature, in pairs.

وَٱلْأَرْضَ مَدَدْنَٰهَا وَأَلْقَيْنَا فِيهَا رَوَٰسِىَ وَأَنۢبَتْنَا فِيهَا مِن كُلِّ زَوْجٍۭ بَهِيجٍۢ

And the earth- We have spread it out, and set thereon mountains standing firm, and produced therein every kind of beautiful growth (in pairs)-

وَجَعَلْنَا فِيهَا رَوَٰسِىَ شَٰمِخَٰتٍۢ وَأَسْقَيْنَٰكُم مَّآءًۭ فُرَاتًۭا

And made therein mountains standing firm, lofty (in stature); and provided for you water sweet (and wholesome)?
