Where the plates meet, their relative motion determines the type of plate boundary (or fault): convergent, divergent, or transform. The relative movement of the plates typically ranges from zero to 10 cm annually. [5] Faults tend to be geologically active, experiencing earthquakes, volcanic activity, mountain-building, and oceanic trench formation.

These smaller plates are often not shown on major plate maps, as the majority of them do not comprise significant land area. For purposes of this list, a minor plate is any plate with an area less than 20 million km 2 (7.7 million sq mi) but greater than 1 million km 2 (0.39 million sq mi).

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 causes the oceanic plate to buckle and usually results in a new mid-ocean ridge forming and turning the obduction into subduction. [citation needed]
The Indian plate is currently moving north-east at five cm (2.0 in) per year, while the Eurasian plate is moving north at only two cm (0.79 in) per year. This is causing the Eurasian plate to deform, and the Indian plate to compress at a rate of four mm (0.16 in) per year. [citation needed]
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 ...
