Are Tectonic Plates In The Asthenosphere at Jack Marco blog

Are Tectonic Plates In The Asthenosphere. Heat from deep within earth is thought to keep the asthenosphere malleable, lubricating the undersides of earth’s tectonic plates and allowing them to move. The tectonic plates connect the parts of earth’s lithosphere, much like the pieces of a jigsaw puzzle. Why are there tectonic plates? In plate tectonics, earth’s outermost layer, or lithosphere —made up of the crust and upper mantle—is broken into large rocky plates. Unlike puzzle pieces, tectonic plates do not rest on a stable surface. Convection currents generated within the asthenosphere push magma upward through volcanic vents and spreading centres to create new crust. These plates lie on top of a partially molten layer.
