What is the average movement of the tectonic plates?
Seven are the major tectonic plates and there is a large number of small plates also available. The average movement amongst these plates is 05 to 10 cm per year, means these plates are continuously moving away from each other.
What plates are not shown on major plate maps?
These 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 20 million km 2 but greater than 1 million km 2 . Nazca Plate – Oceanic tectonic plate in the eastern Pacific Ocean basin – 15,600,000 km 2
