Sentence examples for viscous mantle from inspiring English sources

In particular, landmasses that were once buried under massive glaciers during the last ice age are slowly rising out of Earth's viscous mantle, a glacial rebound that biases instrumentation as much as 10 millimeters per year.

The researchers say this indicates an upper crust made of a mixture of rock and ice in which small craters could be carved supported by a more viscous mantle of ice lower down, which would allow the biggest impact basins to relax away with time, like silly putty returning to its original shape.

In general, after-slip, aftershocks and along-fault migrations of large earthquakes have been described by diffusional processes, which are considered in relation to fault zone rheology (e.g., Savage, 1971; Ida, 1974) together with contributions from viscous mantle rebound which has an affect for much longer periods: a few years (e.g., Lehner et al., 1981).

Then we simulated the falling sea level around the island by reducing the normal forces and monitored the pressure change in the viscous asthenospheric mantle.

Toward the unified simulation of the large deformation of a rigid viscoelastic material (plate) and the convection of a viscous fluid (mantle), an Eulerian scheme with a semi-Lagrangian method is developed.

Senior author Barbara Romanowicz, a UC Berkeley professor of earth and planetary science, noted that the connections between the lower-mantle plumes and the volcanic hotspots are not direct because the tops of the plumes spread out like the delta of a river as they merge with the less viscous upper mantle rock.

The outer layer is a chemically distinct silicate solid crust, which is underlain by a highly viscous solid mantle.

It indicates that the broadscale uplift gradually occurs with negligible change in bulk volume (or density) as viscous asthenosphere and mantle yield to the coseismic stresses.

Given that the African continent is surrounded mostly by oceanic ridges, far-field extension can only be driven by a combination of lateral gradients of gravitational potential energy and viscous coupling with horizontal mantle flow at the base of the lithosphere29,30,31.

I show that the vertical motion of the surface is amplified when a mobile belt is present at the continental margin, with lithospheric mantle less viscous than the cratonic lithosphere and, consequently, more prone to be partially eroded by the convective asthenosphere.

When the ice cap was at its peak 20,000 years ago, its great weight depressed the hot, viscous rocks in the underlying mantle.
