Movement of tectonic plates-higher. Volcanoes, mountains and earthquakes occur at the edges of tectonic plates-their creation depends on the direction the plates are moving.
Why, then, is the inner core solid and the outer core molten instead of the other way around? The inner core of the Earth is solid in spite of the high temperature due to the high pressure. Describe the process of plate tectonics. Give specific examples of geographic features created by plate tectonics. Plate tectonics is the movement of large portions of the crust. The movement is caused by magma squeezing out along the mid-oceanic ridges pushing the plates apart in a process called seafloor spreading. Some geographical features created by plate tectonics include mountain ranges, submarine trenches, island arcs such as Hawaii, and volcanoes.
