Yukio Hattori (服部 幸應, Hattori Yukio, 16 December 1945 – 4 October 2024) was a Japanese television personality who was best known as an expert commentator on the television show Iron Chef. Hattori was also the fifth president of the Hattori Nutrition College ; the Iron Chef end credits mention that the program is "produced in ...
Plate tectonics (from Latin tectonicus, from Ancient Greek τεκτονικός (tektonikós) 'pertaining to building') [1] is the scientific theory that the Earth's lithosphere comprises a number of large tectonic plates, which have been slowly moving since 3–4 billion years ago.
It is known that significant tectonic activity took place before the Indo-Asian collision as terranes were being accreted onto the Eurasian plate during the Late Jurassic-Early Cretaceous, but the extent of deformation and the influence these earlier tectonic events had on the subsequent evolution of the Tibetan Plateau is poorly understood.

Plate tectonics is a theory suggesting that the Earth's lithosphere is essentially composed of plates floating on the mantle. [97] The mantle convection model is fundamental in modeling the plates floating on it, and there are two major approaches to incorporate the plates into this model: rigid-block approach and rheological approach. [2]
Pratt-Hayford Model; where different topographic heights are accommodated by lateral changes in rock density. Vening Meinesz, or Flexural Model; where the lithosphere acts as an elastic plate and its inherent rigidity distributes local topographic loads over a broad region by bending. A cooling and contracting Earth is the prevailing view.
The Vine–Matthews–Morley hypothesis, also known as the Morley–Vine–Matthews hypothesis, was the first key scientific test of the seafloor spreading theory of continental drift and plate tectonics. Its key impact was that it allowed the rates of plate motions at mid-ocean ridges to be computed.
