how plates move and plate boundaries
Tectonic plates are constantly moving, but now the question is-how? They all move depending on the type of boundary they are; either divergent boundary, transform, collisional, or convergent. Those are the four primary types of boundaries. At these differernt boundaries, different things happen. Either mountains, tranches, volcanoes, earthqaukes a At and around convergent boundaries, earthquakes and volcanoes are common. Convergent boundaries move towards each other. Collisional boundaries also includes plates move together, but they form mountains. At transform boundaries, plates slide against eachother. At divergent boundaries, two plates move apart and create new crust by its sea floor spreading technique. Though all plate types move differently and create different things, all plates in general move from convection currents. What are convection currents you ask? Convection currents are the movements of liquid or gas when the warmer liquid rises, the cooler liquid sinks. There is a diagram of this process in the picture at the top of the page. The process of convection currents in Earth can be related to that of which in a convection oven, which has the same concept-moving hot air all around the food to eliminate hot spots and spread heat evenly.
