Answer:-❤
a theory in geology: the lithosphere of the earth is divided into a small number of plates which float on and travel independently over the mantle and much of the earth's seismic activity occurs at the boundaries of these plates.

Hello!!
- Tectonic plates are pieces of Earth's crust and uppermost mantle, together referred to as the lithosphere.
- The plates are around 100 km (62 mi) thick and consist of two principal types of material: oceanic crust (also called sima from silicon and magnesium) and continental crust (sial from silicon and aluminium)
Thanks!!
