Question

almost all tectonic activities occur along the plate boundaries elucidate in four point

Answer 1

Tectonic plates are massive pieces of rock which float on the surface of Mantle. There is a continuous movement in the plates but it is so slow that we cannot feel it. When there is a movement in the plates they move or interact with the bordering plates resulting earthquakes, volcanic eruption, etc. 

Earthquakes, volcanic activity, mountain-building, and oceanic trench formation occur along these plate boundaries.

Tectonic plates are able to move because the Earth's lithosphere has greater strength than the underlying asthenosphere.

Answer 2

Explanation:

almost all tectonic activities occur along the plate boundaries elucidate in four point

When these plates move they interact with the bordering platesresulting earthquakes, volcanic eruption, the formation of mountains, etc. Hence, almost all tectonic activities occur near the borders of the plates (because the collision of plates takes place in the borders of plates)
