Plate Tectonic Theory and the Unification of the Earth Sciences
Overview
It took nearly a century for scientists to accept the idea that continents were not forever fixed in their places, but had, in ...

Convergent Plate Boundary
In terms of plate tectonics, collision boundaries are sites where lithospheric plates move together and the resulting compression causes either subduction (where one or both ...

Plate Tectonics
The important geologic theory of plate tectonics (tecton - "to build") asserts that the Earth's surface is composed of about seven major blocks, or plates, and many more minor plates t...

The basic theory of plate tectonics is that the lithosphere is broken into several parts, or plates, that move over a hot and pliable layer of the mantle. How it pertains to continental drift is that,...
