How do scientists classify the earth's internal layers?

Answer 1

They are classified on their composition (crust, mantle, outer and inner core) and on their mechanical properties (lithosphere, asthenosphere, mesosphere, outer and inner core).

Answer 2

Scientists classify the Earth's internal layers based on their composition and physical properties. The layers are the crust (lithosphere), mantle, outer core, and inner core, each with distinct characteristics such as temperature, pressure, and state of matter. This classification helps scientists understand the Earth's structure and how different layers interact and influence geological processes.
