Web31 mrt. 2024 · Earth’s crust, called the lithosphere, consists of 15 to 20 moving tectonic plates. Why Some plates are moving faster than others? But scientists were at a loss to explain why some pieces of crust move much faster than others. A new study suggests these tectonic plates control their own speed more than the mantle does. Web6 apr. 2024 · Scientists know that these plates move from two different lines of evidence—geodetic and geologic—which allow them to trace their movements back in … The outer layers of Earth are divided into the lithosphere and asthenosphere. The division is based on differences in mechanical properties and in the method for the transfer of heat. The lithosphere is cooler and more rigid, while the asthenosphere is hotter and flows more easily. In terms of heat transfer, the lithosphere loses heat by conduction, whereas the asthenosphere also transfers heat by convection and has a nearly adiabatic temperature gradient. This division should not be confus… import all passwords to settings/passwords
