Web8 sep. 2024 · According to Plate tectonics theory – the lithosphere is believed to have been broken into fragments that are floating on a ductile layer called asthenosphere (upper part of the mantle). The movement of these plates is attributed to the convention currents being generated in the upper mantle.

WebThe lithosphere is not continuous. It is broken into segments called plates. A plate boundary is where two plates meet and move relative to each other. Plate boundaries are where we see plate tectonics in action—mountain building, triggering earthquakes, and generating volcanic activity.
