Question

Why do the plates of the earth move causing tremors on the surface of the earth?

Answer 1

The plates of the earth are in constant motion because of the convection currents in the mantle of the earth.

This process of shifting of the plates is known as continental drift.

This occurs due to the intense amount of heat produced at the core of the earth due to the decay of the radioactive elements.

When the plates move very fast, they cause tremors on the earth’s surface which is referred to as earthquakes.
