What Are Earth's Plates Currently Drifting on

The surface westward drift of the plates demonstrates that differential rotation spin exists between Earths layers. What are plate tectonics.

Plates rotate more slowly than the interior with an average velocity difference of 6 cm year 1.

The theory that explains this process is called plate tectonics. For a detailed analysis of diverse evidence of the importance of spin see Doglioni and Panza 2015.

The Earths crust is made up of huge slabs called plates which fit together like a jigsaw puzzle. These plates sometimes move. An ice age is a long period of reduction in the temperature of Earths surface and atmosphere resulting in the presence or expansion of continental and polar ice sheets and alpine glaciersEarths climate alternates between ice ages and greenhouse periods during which there are no glaciers on the planetEarth is currently in the Quaternary glaciation.

The friction causes earthquakes and volcanic eruptions near the edges of the plates. The theory of plate tectonics is a interesting story of continents drifting from place. They may be on near to or far from tectonic plate boundaries.
