There are not "4 plate tectonics." There are 7 major tectonic plates and many smaller ones. The 7 major plates are:

1. African Plate

2. Antarctic Plate

3. Eurasian Plate

4. Indo-Australian Plate

5. North American Plate

6. Pacific Plate

7. South American Plate

These plates are constantly moving and interacting with each other, causing phenomena like earthquakes, volcanoes, mountain ranges, and the formation of continents and oceans.
