Lots of things happen at the active at the plates. , , and are all results of movement along plate boundaries. Divergent boundaries are where plates are moving and a new crust is created by liquid rock pushing up from the mantel. boundaries are where plates are moving toward each other, and sometimes one plate sinks or is subducted under another. Transform boundaries are where plates horizontally past each other and cause friction. These plates are always moving, slowly the face of the Earth.
