Definitions:

Divergent Boundary

A plate-tectonic boundary in which two plates move apart (diverge) relative to one another.

Convergent Boundary

A tectonic plate boundary where two plates move toward each other, often resulting in mountain building, earthquakes, or volcanic activity.

Transform Boundary

A type of tectonic plate boundary where two plates slide past each other horizontally.

Seafloor Spreading

The process by which new oceanic crust is formed at mid-ocean ridges and slowly moves away from the ridge, contributing to continental drift.
