Movement of Tectonic Plates
Tectonic Plates moves due to the power of the Earth's force which is given out by the inner core. These plates move at about 4 cm a year and in different directions atop a layer of much hotter, softer, more malleable rock called the Athenosphere.
Due to the high temperatures and immense pressures, the uppermost part of athenosphere is deformed and flows almost plasticity just beneath the Earth’s surface. This characteristic of the athenosphere to flow allows the plates to inch along on their endless journeys around the surface of the earth, moving no faster than human fingernails grow.
