How To Use asthenosphere In A Sentence
- Because the downgoing slab of lithosphere is heavier than the plastic asthenosphere below, it tends to sink passively; and the older the lithosphere, the steeper the dip.
- Partial melting models, isotopic studies and the petrology of entrained ultramafic xenoliths suggest that many basanitic magmas are sourced in the asthenosphere.
- Currents beneath the plates move the plates in different directions and driving all this is radioactivity deep in the earth's mantle which keeps the under layer - the asthenosphere - molten.
- Magmas erupted in continental volcanic arcs typically contain components from many sources in the crust, lithospheric mantle and asthenosphere.
- These glide over a weak zone in the mantle known as the asthenosphere, and the relative motion between plates causes most large-scale tectonic structures.
- Because the radioactive source of heat is deep within the mantle, the fluid asthenosphere circulates as convection currents underneath the solid lithosphere.
- The plates constitute the hard lithosphere – literally, ‘sphere of rock’ – which floats atop the hot, semi-molten asthenosphere – ‘sphere of weakness’. THE GREATEST SHOW ON EARTH
- Magmas erupted in continental volcanic arcs typically contain components from many sources in the crust, lithospheric mantle and asthenosphere.
- The asthenosphere, in its capacity as a quasi-liquid, has convection currents that extend throughout its whole surface, under the entire area of the plates. THE GREATEST SHOW ON EARTH
- Asthenosphere uplift indicates the deep adjustment process during the interaction of plates, and also shows the adjusting process of gravitational equilibrium between upper layer of crust and mantle.
