The asthenosphere is the weak and ductile region of the upper mantle of Earth, where partial melting and convection occur. It lies below the lithosphere, at a depth of 80 to 700 km, and is involved in plate tectonic movement and magma generation.
The asthenosphere is a zone of Earth's mantle that is hotter and more fluid than the lithosphere. It lies below the tectonic plates and is involved in plate tectonics, volcanism and earthquakes.
Asthenosphere is a geological term for the thin, almost liquid, layer under the hard rock that forms the outer layer of the earth. Learn more about its properties, structure, and role in magmatism and plate tectonics from Cambridge Dictionary and Wikipedia.
Learn the meaning of asthenosphere, a zone of a celestial body where the material is weak and ductile. See examples, word history, and related entries from Merriam-Webster dictionary.
11 Ιουν 2018 · The asthenosphere is the ductile layer beneath Earth's rigid lithosphere, where tectonic plates move and volcanoes form. Learn about its properties, depth, role in plate tectonics, and how it differs from the lithosphere and the mesosphere.
The asthenosphere is a mechanically weak layer beneath the lithosphere characterized by low seismic wave velocities and high attenuation (Karato, 2012) (Fig. 4.6). It is generally considered to be the source region of ocean-ridge basalts (MORB).
The asthenosphere is a semi-fluid layer of the Earth's upper mantle located below the lithosphere, characterized by its ability to flow slowly over geological time. This layer plays a crucial role in the movement of tectonic plates, allowing for the dynamic processes that shape the Earth's surface, such as earthquakes and volcanic activity.
