what is a direct effect of tectonic plate movement
Finally, as plate tectonics causes the continents to shift position it will have a direct effect on ocean circulation and how heat is distributed around the planet, as well as those continents shifting to different latitudes and climate regimes.
With the change in the tectonic plates, this larger land drifted to form different smaller land areas. Climate is one of the systems adversely affected by these movements. For instance, a larger land area is likely to follow a strong seasonal pattern of climate.
Islands can also occur, but I don't know the specifics. Plate tectonics can cause a number of things. This includes earthquakes when two plates grind together. Earthquakes occur along fault lines, which is why California gets a lot of earthquakes. It is along the San Andreas Fault. Plate tectonics can also cause mountains or volcanoes when one plate goes under another one. That is still happening in most mountain ranges, which is why Mount Everest grows a bit each year.
