Mechanical layering of the earth:
- Lithosphere (solid/rigid), 0-150km
- Asthenosphere (solid/elastic), 150-660km
- Mantle (solid/rigid), 660- 2900km
- Outer core (liquid), 2900-5730km
- Inner core, 5730-6400km
Chemical layering of the earth:
- Crust (oceanic and continental), 0-40km
- Mantle, 40-2900km
- Core, 2900-6400km
The layers of the earth are common to both the compositional and mechanical descriptions is the core and the mantle. The earth has more mechanical layers than compositional layers.
The compositional layers of the Earth are the core,crust and mantle. The physical layers are Asthenosphere and the Mesosphere.
I'm not doing your homework for you!
Earth's layers classified by their composition and their physical properties.
The earth has a total of 6 main layers.

The composition of mercury is solid as well as earth.
sedimenatary rock create layers in the surface of the earth and eruptions from volcanoes also make layers of the earth.

Scientists have been able to determine the composition of earth's layers using various ways. In most cases, samples have been taken and studied so as to determine the layers of the earth.
The earth is composed of three layers. The crust of the earth contains the oceans and land, the mantle which is composed of rocks and precious metals, and the core that is made out of solid iron.

Severals methods are all combined to give the scientist info on the layers of the Earth. For example they study the influence of the earth on orbits of the moon and other planets (mass distribution of the earth, mass density). They study the way seismic waves go through the earth which gives knowledge of layers. They use wave to sound. They examine sample of earth.

There are three main layers based on composition: the crust, the mantle, and the core. There are numerous physical layers. See the link below.
