There are major, minor and micro tectonic plates. There are seven major plates: African, Antarctic, Eurasian, Indo-Australian, North American, Pacific and South American. The Hawaiian Islands were created by the Pacific Plate, which is the world’s largest plate at 39,768,522 square miles.

What is the largest and smallest tectonic plate?
Tectonic plates have a large range of sizes and thicknesses. The Pacific Plate is among the largest, while the disappearing Juan De Fuca Plate is one of the smallest.
Is the Pacific plate the largest plate?
The Pacific Plate is by far the largest tectonic plate on Earth, and its APM relative to the underlying mantle is predominantly determined by negative buoyancy forces related to subduction (e.g., Chapple and Tullis, 1977; Conrad and Lithgow-Bertelloni, 2002; Forsyth and Uyeda, 1975; Hager and O’Connell, 1981; Lithgow- …
Which is the smallest tectonic plate?
One of the smallest of Earth’s tectonic plates, the Juan de Fuca Plate is a remnant part of the once-vast Farallon Plate, which is now largely subducted underneath the North American Plate.

What are the 7 largest plates?
The World Atlas names seven major plates: African, Antarctic, Eurasian, Indo-Australian, North American, Pacific and South American. California is located at the seam of the Pacific Plate, which is the world’s largest plate at 39,768,522 square miles, and the Northern American plate.
How thick are tectonic plates?
Plates are on average 125km thick, reaching maximum thickness below mountain ranges. Oceanic plates (50-100km) are thinner than the continental plates (up to 200km) and even thinner at the ocean ridges where the temperatures are higher.
Are continents the same as plates?
The continents are embedded in the plates. Many continents occur in the middles of plates, not at their boundaries or edges. … Plates are composed of the Earth’s crust and upper mantle, which are collectively called the lithosphere. This layer is like an eggshell compared to the total thickness of the Earth.
What is the future of the Pacific plate?
The Pacific Plate is moving to the northwest at a speed of between 7 and 11 centimeters (cm) or ~3-4 inches a year. The North American plate is moving to the west-southwest at about 2.3 cm (~1 inch) per year driven by the spreading center that created the Atlantic Ocean, the Mid Atlantic Ridge.
Why is Hawaii moving towards Japan?
Hawaii is moving towards Japan at the speed of 10cm a year. This is because they are on different tectonic plates.
How many plates lie under the Pacific Ocean?
Plates that are under the Pacific Ocean include : the Pacific plate, the Nazca Plate, The Cocos Plate, The Juan de Fuca plate, the Philippine Plate and a part of the Indo-Australian Plate.
How many plate tectonics are there in total?
There are seven primary tectonic plates in the world, but there are also seven secondary plates and sixty tertiary plates, for a grand total of more than seventy tectonic plates. Each tectonic plate is approximate 60 miles thick and composed primarily of either continental crust or oceanic crust.
What are the 3 major tectonic plates?
There are three kinds of plate tectonic boundaries: divergent, convergent, and transform plate boundaries.
What are the two largest tectonic plates on Earth?
