The process you're referring to is called subduction. Subduction occurs at convergent plate boundaries where one tectonic plate is forced beneath another plate. As the denser oceanic plate sinks into the asthenosphere, it creates a deep ocean trench on the seafloor.

Is S-wave passes through asthenosphere?

Yes, S-waves do pass through the asthenosphere, although they may be significantly slowed down due to the increased temperature and pressure conditions in this region of the Earth's mantle. The asthenosphere is partially molten and has the ability to transmit S-waves, but their velocity is notably lower compared to the rigid lithosphere above.


The change in velocity of s waves at the top of the asthenosphere suggests that it is?

S waves can only travel though solids. Since they have difficulty traveling through the asthenosphere, we conclude the athenosphere is at least partially fluid.


Why are the crust and upper mantle taken as one layer?

People often confuse the terms 'lithosphere' and 'crust'. The crust is indeed part of the lithosphere, and the lithosphere [minus the crust] is an extension of the mantle.The distinguishing factor between lithospheric (rock-sphere) mantle and the asthenospheric (soft-sphere) mantle is not compositional, but mainly related to temperature and density.At ocean spreading centers, where new lithosphere forms, there is no sharp contrast between the new, warm, thin lithosphere and the upwelling asthenosphere below. In the old, cool, dense lithosphere that makes up ocean basins, the difference between the 'layers' is quite distinguishable.If you look at it from this perspective, the crust is simply coasting atop the lithosphere, getting a free ride. It is the behavior of the mantle, which comprises both the lithosphere and asthenosphere, that controls how plates form, move, and subduct. So yes, the crust is part of the lithosphere, in that it is made up of rocks.Source(s):I'm a geologist/physicist. BLANCHE MARIE PUEBLAS :)

What are some interesting facts about asthenosphere?

by low-density, semiplastic (or partially molten) rock material chemically similar to the overlying lithosphere. The upper part of the asthenosphere is believed to be the zone upon which the great rigid and brittle lithospheric plates of the earth's crust move about (see plate tectonics). The asthenosphere is generally located between 45—155 miles (72—250 km) beneath the earth's surface, though under the oceans it is usually much nearer the surface and at mid-ocean ridges rises to within a few miles of the ocean floor. Although its presence was suspected as early as 1926, the worldwide occurrence of the plastic zone was confirmed by analyses of earthquake waves from the Chilean earthquake of May 22, 1960. The seismic waves, the speed of which decreases with the softness of the medium, passed relatively slowly though the asthenosphere, thus it was given the name Low Velocity zone, or the Seismic Wave Guide (see seismology). Deep-zone earthquakes, i.e., those that occur in the asthenosphere or below it, may be caused by crustal plates sinking into the mantle along convergent crustal boundaries.

What do you call the breaking and vibrating of earth 's crust?

The breaking and vibrating of Earth's crust is called an earthquake. This occurs due to the movement of tectonic plates along faults in the Earth's crust.
