The Earth's compositional layers in order of increasing density are the crust, mantle, outer core, and inner core. The crust is the least dense layer, while the inner core is the most dense layer.
The four principal compositional subdivisions of the Earth are the inner core, outer core, mantle, and crust. The inner core is solid and composed mostly of iron and nickel, the outer core is liquid and also made of iron and nickel, the mantle is a solid rocky layer, and the crust is the outermost layer that we live on.
The Earth's crust is the thinnest compositional layer, ranging from 5 to 70 kilometers thick beneath the oceanic crust and up to 100 kilometers thick beneath continents.
The largest layer of the Earth's surface is the mantle.
No, the mantle is not the bottom layer of the Earth. The mantle is located between the Earth's crust and core, making up a significant portion of the Earth's volume. The core is the deepest layer, found at the center of the Earth.

Core Crust and Mantle
The contour intercal is a layer within the Earth's mantle that separates the upper and lower mantle. It is marked by a change in density and seismic wave velocities, indicating a boundary between different compositional and rheological properties of the mantle. It plays a role in the dynamics of mantle convection and the movement of tectonic plates.

The crust, mantle, and core. :)
The principal divisions of the solid Earth based on compositional differences are the crust, mantle, and core. The crust is the outermost layer and is composed mainly of lighter elements like silicon and oxygen. The mantle lies beneath the crust and consists of denser silicate minerals. The Earth's core is located at the center and is primarily made up of iron and nickel.
The compositional layers refer to the division of the Earth based on the chemical makeup of the layers, such as the crust, mantle, and core. On the other hand, the physical layers are based on the mechanical properties, like the lithosphere (rigid outer layer) and asthenosphere (partially molten layer beneath the lithosphere).
The soft layer of the mantle on which the lithosphere floats is called the asthenosphere. It is a partially molten layer that allows for the movement of tectonic plates due to its weak and ductile properties. The lithosphere, which is the rigid outer layer of the Earth, sits on top of the asthenosphere and moves due to the convection currents in the mantle beneath it.
A mechanical layer refers to a physical layer in a system, such as the structure or components. A compositional layer, on the other hand, refers to the arrangement or composition of materials, elements, or components within a system. In essence, mechanical layer focuses on the physical aspects, while compositional layer focuses on the arrangement or composition of those physical aspects.
Compositional layers refer to the Earth's division based on the materials that make up each layer (crust, mantle, core), while mechanical layers classify the Earth based on how easily each layer can flow or deform (lithosphere, asthenosphere, mesosphere, outer core, inner core). The compositional layers focus on the materials present, while the mechanical layers focus on the physical properties and behavior of each layer.
the difference is that the earth's theory is similar to that of a hypotheses , structure and compositional layer of the earth.
