Web31 de mar. de 2024 · The concept of plate tectonics was formulated in the 1960s. According to the theory, Earth has a rigid outer layer, known as the lithosphere, which is typically about 100 km (60 miles) thick and overlies a plastic (moldable, partially molten) layer called the asthenosphere. Web1 de jun. de 2024 · The tectonic deformation, basin evolution and associated magmatic activities on the overriding plates due to plate interactions along convergent margins may provide primary evidence for our understanding of the dynamics of plate convergence.
