Plate tectonics is known as one of the fundamental theoretical breakthroughs in natural sciences in the 20th century. In the 60 years since its advent, many papers have been published to suggest when plate tectonics should begin, but due to the unclear interpretation of relevant geological observation data and the different weightings of different types of data, researchers propose the time of the plate tectonics onset covering most of the Earth's history (Precambrian). In addition, the thermal state of the Earth, the trigger for global plate tectonics, and differences in the crust-mantle interaction in the early and late Earth are also controversial. The project is to characterize the time of origin and evolution of plate tectonics in different geoscientific contexts. Numerical models are developed under reasonable physical constraints to further analyze the reasons for the evolution of ancient tectonics to modern plate tectonics, as these aspects are inextricably linked to the interactions between Earth's layers, the origin of life, and the habitability of the Earth.
