A sword smashed into the ground hard enough will totally kick rocks and dirt and stuff up. And if warriors could summon rocks why the hell can't I use the ability to start avalanches onto mine enemies.
Actually the sword would just break, or sink into the ground.
But a humanoid is not capable of hitting a sword into the ground as hard as the animation wants you to think, unless they are using magic to increase the force that the sword is delivering, either by increasing the speed of the sword swing or increasing the mass of the sword of using the sword to delivery a type of force magic. All of which would require magic.
