What are the 8 plate tectonics?
Most of the Earth is covered by seven major plates and another eight or so minor plates. The seven major plates include the African, Antarctic, Eurasian, North American, South American, India-Australian, and the Pacific plates. Some of the minor plates include the Arabian, Caribbean, Nazca, and Scotia plates.
How are tectonic plates mapped?
The modern Earth’s tectonic plate boundaries are mapped in excruciating detail. In the modern Earth, global positioning satellites are used to map how the Earth changes and moves.
What is a plate boundary map?

What are tectonic plates Class 9?
A Tectonic plate (also called lithospheric plate) is a massive, irregularly shaped slab of solid rock, generally composed of both continental and oceanic lithosphere.
Is Australia on a tectonic plate?
Australia is located centrally on the Australian plate, and is remarkably stable tectonically, with most of the coast classified as a passive margin or trailing edge.
Where is the Pacific Plate?
The Pacific Plate is an oceanic tectonic plate that lies beneath the Pacific Ocean. At 103 million km2 (40 million sq mi), it is the largest tectonic plate. The Pacific Plate contains an interior hot spot forming the Hawaiian Islands.
Where are all of the tectonic plates located?

What are the nine major tectonic plates?
There are 7 primary plates (Pacific, North America, Eurasia, Africa, Indo-Australian, Antarctica, and South America) that make up the majority of the earth’s surface and the Pacific Ocean. Then there are secondary plates such as the Caribbean, the Cocos, the Juan de Fuca, the Nazca, the Philippines Sea, and the Scotia.
