The movements of the plates its responsible of the moves of the boundaries three types of boundaries such are Convergent boundaries, divergent boundaries and transform boundaries, the visual effects of those boundaries is create mountains, volcano’s, faults, subduction zone, tsunamis and earthquakes. The cause of those important movements it’s the convections currents (move of the mantle inside in the earth) the continental drift is a good example to showed of the movements of the continents around the earth so this couple things take part of important movements of the earth all this beautiful things is caused by boundaries movements by sometime this movements could create a disaster.
