Question

what is tectonic plates

Answer 1

Tectonic Plates - 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.

Answer 2

Small plates into which the earth's crust (lithosphere) is divided are known as tectonic plates. The interaction or interlocking of these plates cause disturbance in the earth's lithosphere which is commonly termed as earthquake.
