Plate tectonics (from Latin tectonicus, from Ancient Greek τεκτονικός (tektonikós) ' pertaining to building ') [1] is the scientific theory that the Earth's lithosphere comprises a number of large tectonic plates, which have been slowly moving since 3–4 billion years ago.

Convergent boundaries are areas where plates move toward each other and collide. These are also known as compressional or destructive boundaries. Obduction zones occurs when the continental plate is pushed under the oceanic plate, but this is unusual as the relative densities of the tectonic plates favours subduction of the oceanic plate. This ...

The Caribbean plate is moving eastward about 22 millimetres (0.87 in) per year in relation to the South American plate. [6] [7] In Venezuela, much of the movement between the Caribbean plate and the South American plate occurs along the faults of Boconó, El Pilar, and San Sebastián. [5] The western portion of the plate is occupied by Central ...
In plate tectonics theory during the breakup of a continent, three divergent boundaries form, radiating out from a central point (the triple junction). One of these divergent plate boundaries fails (see aulacogen) and the other two continue spreading to form an ocean.

After breakup from Gondwana (the southern part of the supercontinent Pangea), the Antarctic plate began moving the continent of Antarctica south to its present isolated location, causing the continent to develop a much colder climate. [2] The Antarctic plate is bounded almost entirely by extensional mid-ocean ridge systems.
