Where the plates meet, their relative motion determines the type of boundary: convergent, divergent, or transform. Earthquakes, volcanic activity, mountain-building, and oceanic trench formation occur along these plate boundaries. The lateral relative movement of the plates typically ranges from zero to 100 mm annually.
This is a list of tectonic plates on Earth. Tectonic plates are pieces of Earth's crust and uppermost mantle, together referred to as the lithosphere.hese smaller plates are often not shown on major plate maps, as the majority do not comprise significant land area. For purposes of this list, a minor plate is any plate with an area less than 10 million km 2 but greater than 1 million km 2.
