A connection between earthquakes and volcanic activity has probably been suspected since the earliest history of mankind. But it is the theory of Plate Tectonics to allow explaining the deeper relationship between the two phenomena and explaining both of them in a single unifying theory. ...
1.(used with a sing. verb)A theory that explains the global distribution of geological phenomena such as seismicity, volcanism, continental drift, and mountain building in terms of the formation, destruction, movement, and interaction of the earth's lithospheric plates. ...

The distribution of the diapiric granitoids that intrude this cover points to a honeycomb convection centred on downwelling sites separated by diffuse upwelling, which fits the theory on the early Earth mantle convection when plates did not cover the globe. We propose that the plate reorganisation ...
the southern margins of the plates are usually characterized by the presence of the An- dean-type geosyncline or the trench-island are-type geosyncline,the northern margins of the plates by the presence of the Atlantic-type eugeosyncline,and the middle part of the plates by the presence of ...

An enduring question in geology is when Earth's tectonic plates began pushing and pulling in a process that helped the planet evolve and shaped its continents into the ones that exist today. Some researchers theorize it happened around four billion years
The theory of plate tectonics explains how the crust of the Earth is made of several plates, large areas of crust which float on the Mantle. Since these plates are free to slowly move, they can either drift towards each other, away from each other or slide past each other. Many earthquak...
plate tectonics is the theory that earth’s outer shell is divided into several plates that glide over the mantle, the rocky inner layer above the core. the plates act like hard and rigid shells compared to earth’s mantle. this strong outer layer is called the lithosphere. the earth’s ...
