A package of sediments scraped off the downgoing lithospheric plate will deform until it and the accretionary prism that it has been added to attain a critical taper ( constant slope ) geometry.

The age is often equal to L / V, where L is the distance from the spreading centre of mid-oceanic ridge, and V is velocity of the lithospheric plate.
13.
The trend of a seamount chain traces the direction of motion of the lithospheric plate over a more or less fixed heat source in the underlying asthenosphere part of the Earth's mantle.

This supports the theory of " Continental Drift " and " Plate Techtonic " which says the Earth's lithospheric plates move about a few centimeter a year ( as fast as your fingernails grow)
15.
According to the theory of plate tectonics, Earth's surface is broken into thick, rigid slabs called lithospheric plates, which slowly move about; atop them ride the continents, like logs stuck in ice.
16.
Additionally, plates in viscoelastic-plastic models have no deformation memory, i . e . as soon as the stress on a lithospheric plate drops below its yield stress it returns to its pre-deformation strength.

A mesoplate , then behaves like lithospheric plates : empirical evidence ( discussed above ) indicates groups of melting anomalies ( hotspots ) embedded in the shallow mesosphere do not move relative to one another, but collectively move relative to other hotspot groups and relative to overlying lithospheric plates.

Since the hotspots of the Hawaiian set appear to form a frame of reference ( like points on a lithospheric plate, they don't appear to be moving at a very great rate relative to one another ), the hotspots and that part of the upper mantle in which they are embedded is termed the " Hawaiian mesoplate ".
20.
Areas of the crust where new crust is created are called " divergent boundaries ", those where it is brought back into the Earth are " convergent boundaries " and those where plates slide past each other, but no new lithospheric material is created or destroyed, are referred to as transform ( or conservative ) boundaries Earthquakes result from the movement of the lithospheric plates, and they often occur near convergent boundaries where parts of the crust are forced into the Earth as part of subduction.
