Map showing Earth's principal tectonic plates and their boundaries in detail. These plates comprise the bulk of the continents and the Pacific Ocean.For purposes of this list, a major plate is any plate with an area greater than 20 million km 2 (7.7 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 Amurian plate, the Okhotsk microplate, and the Philippine Sea plate meet in Japan near Mount Fuji. (see Mount Fuji's Geology) The Azores triple junction is a geologic triple junction where the boundaries of three tectonic plates intersect: the North American plate, the Eurasian plate and the African plate, R-R-R.

Plate tectonics (from Latin tectonicus, from Ancient Greek τεκτονικός (tektonikós) 'pertaining to building') is the scientific theory that Earth's lithosphere comprises a number of large tectonic plates, which have been slowly moving since 3–4 billion years ago.
The Rodrigues triple junction viewed from south. Note the "wake" of the eastward propagating triple junction. The Rodrigues triple junction (RTJ), also known as the central Indian [Ocean] triple junction (CITJ) is a geologic triple junction in the southern Indian Ocean where three tectonic plates meet: the African plate, the Indo-Australian plate, and the Antarctic plate.
Plate tectonics (from Latin tectonicus, from Ancient Greek τεκτονικός (tektonikós) 'pertaining to building') [1] is the scientific theory that Earth's lithosphere comprises a number of large tectonic plates, which have been slowly moving since 3–4 billion years ago.
In the heart of Asia, deep underground, two huge tectonic plates are crashing into each other — a violent but slow-motion bout of geological bumper cars that over time has sculpted the soaring ...
The North American plate is a tectonic plate containing most of North America, Cuba, the Bahamas, extreme northeastern Asia, and parts of Iceland and the Azores.With an area of 76 million km 2 (29 million sq mi), it is the Earth's second largest tectonic plate, behind the Pacific plate (which borders the plate to the west).
