WebThe asthenosphere has a convection current, made by magma swirling around in a circular motion, from top to bottom. The convection current is what makes the plates move. The asthenosphere is part of a gigantic layer that takes up a full 2/3 of the Earth's radius: the mantle. The asthenosphere is part of the upper mantle, closest to the crust. WebThe Moho marks the transition in composition between the Earth's rocky outer crust and the more plastic mantle. Immediately above the Moho, the velocities of primary seismic waves (P-waves) are consistent with those through basalt (6.7–7.2 km/s), and below they are similar to those through peridotite or dunite (7.6–8.6 km/s).
