The right order is: From the centrer of earth :
1. Inner core
The inner core is the solid part in the center of the Earth. It's like a ball of 1,200 kilometers in diameter located in the center of the outer core (liquid). It is composed of an alloy of iron and nickel, as well as lighter elements.
2. Outer core
The outer core is the liquid part of the Earth's core, located above the inner core and below the Earth's mantle. Like the inner core, the core is a metal alloy, consisting mainly of iron and nickel. The liquid of the outer core is animated by rapid convective movements which are the origin of the Earth's magnetic field.
3. Lower mantle
The lower mantle has solid properties at timescales less than the year, and plastics at time scales greater than the century.
In the lower mantle, mantle convective cells are slow moving matter. Indeed, the mantle is the seat of convection currents that transfer most of the heat energy from the Earth's core to the surface. These currents cause continental drift, but their precise characteristics (speed, amplitude, location) are still poorly known.
4. Upper mantle (asthenosphere)
The upper mantle and the crust form the lithosphere, which can reach 300 km below the continents. The part of the lithosphere that is not the crust is very brittle. From 200 to 700 km deep, we find the "asthenosphere", which is the plastic part of the upper mantle.
5. Crust (lithosphere) : the most eccentric layer of these statements
The earth's crust, is the superficial and solid part of the material from which the Earth is made. This is the upper part of the lithosphere (which constitutes the tectonic plates).
The separation between the upper mantle and the Earth's crust is called the Mohorovicic discontinuity.
