What physical mechanism primarily leads to the eventual dispersal of an open cluster residing in the galactic disk?

Answer

Gravitational disruptions caused by the larger structure of the galaxy

The initial density of an open cluster is often insufficient to counteract gravitational disruptions from passing stars, giant molecular clouds, and the non-spherical gravity of the galactic disk structure.
