Lithosphere moves over mantle plumer

Web9 mrt. 2016 · The Lithosphere is made up of solid rock. Composition: Oxygen, silicon, aluminum, iron, calcium, and sodium 4. Asthenosphere The plates of the Lithosphere move (or float) on this hot, malleable semiliquid zone in the upper mantle, directly underneath the Lithosphere. The Asthenosphere is made up of solid rock, just like the Lithosphere. 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. Asthenosphere
