There are actually four layers.
The crust is the outermost layer of the earth, made of soil and bedrock, containing 60.6 percent silicon dioxide, 15.9 percent dialuminum trioxide, and other minor minerals. The mantel is directly beneath the crust, and is about 1,800 miles deep, containing 85 percent of the earth's weight and mass, and is molten rock. The outer core is next, about 1,200 miles deep, going down to about 3,000 miles. It is believed to be made of super-heated lave made of iron and nickel. Even deeper is the inner core, which is about 900 miles deep, and is a solid ball of super-heated iron and nickel. It is not molted because there is too much pressure on it, therefore stopping it from expanding and melting.

Compare Earth's compositional layers with its structural layers?
Earth's compositional layers are the crust, mantle, and core, based on the materials they are made of (silicates vs. metals). Structural layers are based on their physical properties and include the lithosphere, asthenosphere, mesosphere, outer core, and inner core. The main difference is that compositional layers are defined by chemical differences, while structural layers are based on physical properties like temperature and behavior.
Compare the three compositional zones of earth with the five structural zones of earth?
The three compositional zones of Earth are the crust, mantle, and core, based on their chemical composition. The five structural zones of Earth are the lithosphere, asthenosphere, mesosphere, outer core, and inner core, based on their physical properties and behavior. The compositional zones focus on the materials present, while the structural zones consider how these materials behave and interact within the Earth's interior.
What are the principal divisions of the solid earth based on compositional differences?
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.
What are three layers of the earth from the most outer to the most inner?
The three layers of the Earth from the outermost to the innermost are the crust, the mantle, and the core. The crust is the Earth's outer shell, the mantle is a semi-solid layer beneath the crust, and the core is the Earth's innermost layer, consisting of a solid inner core and a liquid outer core.
What are the 3 main layers of the earth?
The three main layers of the Earth are the crust, mantle, and core. The crust is the outermost layer that we live on, the mantle is a thick layer beneath it, and the core is at the center of the Earth.
What are three compositional layers of the earth?

Is not one of the compositional layers of earth?
The Earth is composed of three primary layers: the crust, mantle, and core. If something is not one of these layers, it could be referring to phenomena such as the atmosphere or hydrosphere, which are not considered compositional layers of the Earth. Instead, they represent different components of the Earth's environment.
Compare Earth's compositional layers with its structural layers?
Earth's compositional layers are the crust, mantle, and core, based on the materials they are made of (silicates vs. metals). Structural layers are based on their physical properties and include the lithosphere, asthenosphere, mesosphere, outer core, and inner core. The main difference is that compositional layers are defined by chemical differences, while structural layers are based on physical properties like temperature and behavior.
What are the three features of the three compositional layers of earth?
Crust: very thin, rocky and well.. Crusty. Is broken into smaller parts called techtonic plates. Mantle: the biggest part, made mostly of moltent iron. Core: the hottest part, also made of molten iron, but is much hotter that the mantle, but smaller sinc its in the centre of the earth.
