asthenosphere उदाहरण वाक्य

One theory states that variations in lithospheric thickness between the Baikal rift and the Siberian platform generate a convection current in the asthenosphere.
After they penetrate the asthenosphere, Steven takes note of the fact that there is a lava-like substance all around them.
Such old continental crust and the underlying mantle asthenosphere are less dense than elsewhere in Earth and so are not readily destroyed by subduction.
The rigid lithosphere is thought to " float " or move about on the slowly flowing asthenosphere, creating the movement of tectonic plates.
Potential energy that drives the delamination is released as the low density, hot asthenosphere rises and replaces the higher density, cold lithosphere.

To compensate for lithospheric thinning, asthenosphere upwells, melts due to adiabatic decompression, and derivative melts rise to the surface to erupt.
Heating caused by the rise of warmer asthenosphere created a crustal low-viscosity zone and delamination occurred on the flanks of the Basin and Range.
In either case, the unsettled asthenosphere might have experienced low degrees of decompressional melting and interacted with North American lithosphere to yield within plate compositions.
It has generally been accepted that tectonic plates are able to move because of the relative density of oceanic lithosphere and the relative weakness of the asthenosphere.
Forearcs have the lowest heatflow from the interior Earth because there is no asthenosphere ( convecting mantle ) between the forearc lithosphere and the cold subducting plate.
