Webb2 sep. 2024 · Plate tectonics, in brief, states that the Earth's surface is broken into plates. Each plate consists of slabs of lithosphere, the rocky outer layer of the Earth, that includes the crust and uppermost mantle. These lithospheric pieces move on top of the asthenosphere, a plastic layer within the mantle. Webb7 juli 2024 · The asthenosphere 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.
