Answer:
The 3 main layers are the core, mantle and crust. The mantle is composed of the mesosphere and the asthenosphere and the uppermost part of the mantle. That uppermost part of the mantle is what is combined with the crust to make the lithosphere.The inner core is solid, the outer core is liquid, and the mantle is solid/plastic. This is due to the relative melting points of the different layers (nickel–iron core, silicate crust and mantle) and the increase in temperature and pressure as depth increases We have the inner core, outer core, mantle and crust which play an important role on Earth. The layers of the Earth are responsible for the formation of our continents. ... Earthquakes can be important because of Energy (seismic energy) released during Earthquakes provides much information about the Earth's interior.
