At convergent boundaries, tectonic plates interact primarily through collision, which results in various geological phenomena such as subduction, mountain building, and earthquakes. When two plates converge, one plate may be forced underneath another in a process known as subduction. This is common in oceanic-continental boundaries where the denser oceanic plate is pushed under the lighter continental plate, leading to the formation of deep ocean trenches and volcanic activity.

In cases where two continental plates collide, neither plate is subducted to a significant extent, resulting instead in significant mountain building, such as the Himalayas formed from the collision of the Indian and Eurasian plates. Furthermore, the immense pressure and friction from the collision of the plates can lead to earthquakes as the plates become stuck and then suddenly release.

The other choices describe interactions that do not occur at convergent boundaries. Sliding past each other pertains to transform boundaries, separation refers to divergent boundaries where new crust is formed, and the idea of floating above each other without interaction does not accurately represent the dynamic interactions that occur at convergent boundaries.
