Summary

In fact, the entire earth is located on 12 tectonic plates. These plates rotate at a very slow speed and move 4 to 5 mm every year. While rotating, if any plate reaches too far from another or slides down, then they collide with each other. Energy is released during collision, which is called earthquake.

The Earth is made up of a total of seven landmasses. This includes Indian-Australian landmass, North American landmass, Pacific Ocean landmass, South American landmass, African landmass, Antarctic landmass, Eurasian landmass.
