Paleomagnetism support plate tectonics
WebTypes of plate boundaries — There are three types of boundaries between lithospheric plates (Fig. 3): 1) convergent boundary — plates converge, or come together. If a plate of oceanic lithosphere collides with thicker and less dense continental lithosphere, the denser oceanic plate will dive beneath the continent in a subduction zone (Fig. 2).
