Answer 2

The seven layers of the Earth are( starting from the outermost layer):

Crust- outer silicate crust(Oceanic and continental); solid in nature

Lithosphere

Asthenosphere- viscous in nature

Mantle- Outer and inner- viscous in nature

Outer core- liquid

These layers have been determined by topographical and bathymetric observations, also by studying rock samples from volcanoes, and analysing seismic waves.
