What phenomenon is responsible for dispersing heavy elements across the interstellar medium following a core-collapse supernova?
Answer
The explosion dispersing the star's outer layers
The supernova explosion ejects the star's outer layers, which have been enriched with heavy elements forged both during the star's life and during the supernova event itself, scattering these materials into space.
