Question

The hot, partially melted, slowly flowing layer of Earth is called the ____. a. lithosphere b. outer core c. asthenosphere d. inner core

Answer 1

The asthenosphere, it is the denser, weaker layer beneath the lithospheric mantle. It lies between about 100 kilometers (62 miles) and 410 kilometers (255 miles) beneath Earth's surface. The temperature and pressure of the asthenosphere are so high that rocks soften and partly melt, becoming semi-molten.
