Plate convergence is the phenomena of two plates moving toward one another. [Wikipedia]
Plate divergence is the phenomena of plates drifting apart [Wikipedia]
A tectonic ssemblage is a geological term for an accreted terrane of heterogeneous rocks. [Wikipedia]
A terrane in geology is a fragment of crustal material formed on, or broken off from, one tectonic plate and accreted — "sutured" — to crust lying on another plate. [Wikipedia]
Asymmetric heat flow in geology is an observation that the heat from upwelling mantle does not spread symmetrically away from the hot spot or rift due to differences in crust composition.
Continental drift is the movement of the Earth's continents relative to each other. [Wikipedia]
An extension event occurs when a seismic event causes an extension in the crust. [Wikipedia]
Post-glacial rebound (sometimes called continental rebound, isostatic rebound, isostatic adjustment or post-ice-age isostatic recovery) is the rise of land masses that were depressed by the huge weight of ice sheets during the last glacial period, through a process known as isostatic depression. [Wikipedia]
A spreading event occurs whenever plates drift apart (Plate Divergence). [Wikipedia]
The tectonic force is the force created by one tectonic plate pushing against another due to upwellings of the mantle, [Wikipedia]
The tectonic phenomena is the observable motions of the tectonic plates in the Earth's Lithosphere. [Wikipedia]
