This movement of one tectonic plate contributing to the growth of the mountain chain will primarily: return carbon to the ocean through weathering.
Depending on how they are defined, the lithosphere of Earth, which is the solid outermost shell of the planet (the crust and upper mantle), is divided into seven or eight major plates and several lesser plates or "platelets." The type of plate boundary—convergent, divergent, or transform—where the plates converge depends on their relative motion. Along these plate borders, earthquakes, volcanic eruptions, mountain-building, and oceanic trench development take place (or faults). The plates typically move relative to one another by zero to ten centimeters per year.
