Respuesta :
the first joint of my index finger and the middle knuckle of my thumb I have small hands so I might be diffrient from yours and it symbolizes the plates touching I. getting bumped from other plates (tectonic)
The pressure is felt mostly along the index fingers. The two hands model two plates. So, just as the index finger feels the most pressure when the hands are pushed together, two plates moving together create high pressure along the boundary between them.
