Step-by-step explanation:
The trick that involves a 540-degree rotation and a shove-it in skateboarding is known as a 540 Shove-it. This is a more advanced trick where the skateboarder makes the board rotate 540 degrees while also doing a shove-it, which means the board spins underneath them while they jump and land back on the board. To perform this trick, the skateboarder typically initiates a pop shove-it, then adds extra rotation to complete the 540 degrees.
