Which primary outcome results from tectonic plate divergence?

💡 Explanation

Divergence leads to decompression melting of the asthenosphere and magma formation; thus, seafloor spreading leads to creation of new oceanic crust via basalt eruptions due to ridge push, rather than other plate interactions because subduction forms stratovolcanoes.
