Question

what are tectonic plates

Answer 1

 A tectonic plate (also called lithospheric plate) is a massive, irregularly shaped slab of solid rock, generally composed of both continental and oceanic lithosphere.

Answer 2

Tectonic plates are huge and irregular slabs of rock into which the lithosphere of the earth is broken.

EXPLANATION:

"Lithosphere" is the "Outermost layer" of the earth that contains the crust and solid rocks.

There are 'seven' major "tectonic plates" on the earth which are under the continents and oceans. In addition to these, the earth also has several smaller tectonic plates.

Tectonic plates usually float on the asthenosphere. These plates move slowly and rub against each other which cause the volcanic and seismic activities on the earth.
