The asthenosphere is like a slow-moving river of molten rock that the crust, broken into different plates, moves on top of.
The asthenosphere is the denser, weaker layer below the lithospheric mantle. It lies among approximately a hundred kilometers (sixty two miles) and 410 kilometers (255 miles) below Earth's floor. The temperature and pressure of the asthenosphere are so excessive that rocks soften and in part melt, becoming semi-molten.
The asthenosphere is the robotically weak and ductile place of the upper mantle of Earth. It lies underneath the lithosphere, at a intensity among ~80 and 200 km under the surface, and extends as deep as seven hundred km. however, the decrease boundary of the asthenosphere is not properly defined. asthenosphere, sector of Earth's mantle mendacity underneath the lithosphere and believed to be lots hotter and extra fluid than the lithosphere. The asthenosphere extends from approximately 100 km (60 miles) to about seven hundred km.
