Earthquake

The Earth's structure has three parts — 

1. an outer silicate solid crust (till about 30km from the surface), 
2. a viscous mantle (2,900km thick) below the crust and 
3. a core (3,500km diameter) at the center. 

The uppermost part of the mantle and the crust is broken into seven major tectonic plates — 

1. African, 
2. Australian, 
3. Eurasian, 
4. North American, 
5. South American, and 
6. Pacific. 

The motion of these plates against each other causes earthquakes.
