Plate Tectonics May Have Been Agile Since The Inception Of Earth

Plate-Tectonics-May-Have-Been-Agile-Since-The-Inception-Of-Earth

A contemporary study indicates that plate tectonics defined as a process by which Earth is divided into massive slabs of crust that maneuver steadily on top of hot viscous mantle rock, could have been kicking and active since the inception of the Earth. The contemporary discoveries ignore former ideologies that tectonic plates were evolved over a time span of billions of years.

This study has significant insinuations in the areas of geochemistry and geophysics. For example a superior comprehension of plate tectonics could assist foretelling if planets far away from solar system could be congenial to life.

Nick Dygert, assistant professor of petrology and geochemistry in UT’s Department of Earth and Planetary Sciences said that plate tectonics are the basis of setting state for life. The additional information we get on plate tectonics the better we will comprehend about the birth and evolution of Earth. For the research, Dygert and his team probed the dispersal of two extremely particular noble gas isotopes:  Helium-3 and Neon-22. Noble gases are those that do not react to any other chemical element.

Earlier models have elucidated Earth’s present Helium-3/Neon-22 ratio by debating that a succession of massive scale collision ensued in enormous magma oceans which degassed and progressively expanded the ratio each time. But Dygert supposes that the scenario is improbable.

He also added that while there is no incontestable proof that this did not occur. It could have only elevated the Earth’s Helium-3/Neon-22 ratio under extremely particular constraints.
