(2020-07-20)
A new idea on how Earth's outer shell first broke into tectonic plates
Plate tectonics theory posits that Earth's outer shell is subdivided into plates that move relative to each other, concentrating most activity along the boundaries between plates, yet the scientific community has no firm concept on how plate tectonics got started. (2020-07-19)
