She stands there and considers the rocks for a bit. Takes a deep breath and stretches slightly, thinking about it.
She should just feel it out, right?
Stretch her arms, stretch her legs, get into a basic karate stance. She doesn't remember actual Earthbending forms but just imitating them should help.
Focus on the gravel. It feels distinct to her weird earthsense. Feet wide and firmly planted. Stand straight, deep breath, tail touching the ground. She holds one arm out and slowly lifts and pushes her will into the gravel.
It's a bit more dramatic than she expected, a major chunk of gravel rises up, individual rocks falling off the mass in a steady stream. She feels the sudden strain drawing on her, not physical, but on her mana.
She blinks and loses more gravel from the chunk and quickly maneuvers it over to the frame.
