Water and rocks

[Rockstar]

"Water is fluid, soft, and yielding. But water will wear away rock, which is rigid and cannot yield. As a rule, whatever is fluid, soft, and yielding will overcome whatever is rigid and hard. This is another paradox: What is soft is strong."
-Lao-Tzu


In case anyone is near Delmarva and wondered where that smoke on the horizon was coming from. Its me thinking.

Why does water carve a rock? Its is a fluid made up of two Hydrogen molecules and one Oxygen molecule. It carries with it abrasives which scour away a rock. Also too when a certain amount of force (flow) of water alone is applied for a determined amount of time. It has enough energy to break loose and carry away mineral molecules that make up the rock.

If water has directed energy, water molecules will carry away steel molecules too. Nobody thinks gas as being hard either. But watch a meteor vaporize and scatter when it hits earth's atmosphere.

Seems to me rock is softer and more yielding than water or gas.
