Answer:
No one has ever been able to show exactly when plate tectonics began. Several studies had pegged the beginning of plate tectonics at around 3 billion years ago, but the new research suggests this dynamic started 3.5 billion years ago — only about a billion years after the formation of the planet.
Explanation:
Whatever the Earth looked like before plate tectonics, these powerful forces define the world as it is today. The diving and crashing of tectonic plates not only created the continents we know and live upon today, it also recycles minerals and nutrients through Earth's system. One 2014 study in the journal Proceedings of the National Academy of Sciences, for example, argued that the formation of continents on early Earth brought phosphorous to the surface, feeding microbes that then oxygenated the atmosphere.

No one has been able to pinpoint exactly when plate tectonics began. Some studies suggest that plate tectonics started about 3 billion years, but new studies suggest that these dynamics started 3.5 billion years after the formation of the planet, or about 1 billion years later. It has been.
Plate Tectonics Whatever the pre-Earth was, these powerful forces define the world today. The diving and collapse of plate tectonics not only created the living continents we know today but also recycles minerals and nutrients through the Earth's system. For example, a 2014 study by the National Academy of Sciences journal Proceedings claimed that the early formation of continents on Earth brought phosphorus to the surface, supplying microorganisms, which oxygenated the atmosphere.
Chemoheterotrophs was the first organism to form life on earth.
Hence concluded that few remaining samples of these early rocks remain as it usually gets destroyed.
