What is the best description of a convergent boundary? (Do they move towards eachother, side by side past each other, away from each other, or are they attracted to each other by gravity)

Convergent boundaries move towards each other. They can be classified as continental-continental, or oceanic-continental.

Oceanic-Continental: Heavier oceanic plate slides under a continental plate in a process called subduction.

Continental-Continental: Tectonic plates push up against each other and often fold upwards, creating mountain ranges.
