They were calculated from systematic, extensive analysis of seismic vibrations (from earthquakes).
Continents drift on top of the upper mantle. The core is much further down.
No, the core is hotter.

The area nearest to the Earth's Core.
The layers of Earth's interior are the crust, mantle, outer core, and inner core. The crust is the outermost layer, followed by the mantle which is divided into the upper and lower mantle. The outer core is liquid and the inner core is solid.

The crust, mantle, inner core, and outer core.
Inner core (probably solid); outer core (probably liquid); mantle, crust.
The three parts that make up the Earths mantle are the crust, core, and mantle.
