Tectonic Plates Shift, Earthquakes Devastate World
- The Earth's crust is composed of 12 major tectonic plates that constantly shift against each other due to the superheated magma beneath them, causing earthquakes along the plate boundaries.
- Earthquakes can be devastating, with the most violent type occurring in subduction zones where one tectonic plate is forced beneath another, leading to destructive seismic shock waves and potentially triggering tsunamis, resulting in significant casualties worldwide.
