Starting on the surface: crust, upper mantle, lower mantle, outer core, inner core.
1. The Crust--The outer skin of the planet is composed of igneous, metamorphic, and sedimentary rock.
2. The Upper Mantle--Lithosphere: The uppermost mantle consists of hard rock and is attached to the crust and comprises the lithosphere. The lithosphere is comprised of tectonic plates which 'float' independently of each other. The lithosphere contains more mantle than crust. Oceanic lithosphere ranges from 50 km to 100 km in thickness, and continental lithosphere ranges from 40 km to 200 km. Asthenosphere: Just below the lithosphere lies the asthenosphere, an area of highly viscous but solid rock. Its viscosity allow it to move slowly over time, which it does as it transfers heat to the lithosphere via convection currents. These convection currents are responsible for the movement of Earth's tectonic plates. The depth of the asthenosphere averages somewhere between 100 km and 200km with depths up to 410 km.
3. The Lower Mantle--The depth of the lower mantle ranges from 670 km to 2798 km. Little is known about the lower mantle other than that seismic waves indicate it is fairly homogenous in lithology.
4. The Outer Core--The outer core lies at a depth from 2900 km to 5150 km. It's composed of liquid iron and nickel along with small amounts of lighter elements, with temperatures ranging from 4,000 degrees C to 6,100 degrees C near the boundary with the inner core.
5. The Inner Core--From the boundary with the outer core to the center of the Earth, a distance of about 1220 km is the solid sphere of the inner core, a ball of incredibly hot iron-nickel alloy. Temperatures here reach between 5,000 and 7,000 degrees C, and pressures are calculated to be around 3,000,000 units of atmospheric pressure. Despite the high temperature, at these pressures the metals cannot remain molten.

What are the 5 LEVELS of the Earth?
The five layers of the Earth are the inner core, outer core, mantle, lithosphere, and crust. These layers differ in composition, temperature, and physical properties, forming the structure of the Earth.
Does earth have five layers?
No, Earth has four main layers: the crust, mantle, outer core, and inner core. These layers differ in composition, density, and physical properties, and together they make up the structure of the Earth.
Are the Earth's 5 physical layers these Inner Core Outer Core Mesosphere Asthenosphere and Lithosphere?
The Earth's five physical layers are actually the Inner Core, Outer Core, Mantle, Asthenosphere, and Lithosphere. The Mantle is an additional layer between the Outer Core and the Asthenosphere, which plays a crucial role in Earth's structure and dynamics.
Are the five layers of the atmosphere in earth or out of earth?
The five layers of the Earth's atmosphere are within the Earth, as part of the planet's atmosphere. These layers include the troposphere, stratosphere, mesosphere, thermosphere, and exosphere.
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.

Are there five physical layers of earth?
No, Earth's structure is typically divided into four main layers: the inner core, outer core, mantle, and crust. Each layer is characterized by different physical and chemical properties, with the inner core being solid, the outer core being liquid, the mantle being solid but capable of flowing, and the crust being solid and relatively thin compared to the other layers.
What are the five layers of us based on physical properties?
We are all made out of a mass of molecules and a complex molecular structure.
What are the 5 sub-layers of the earth?
The five sub-layers of the Earth are, from outermost to innermost: the lithosphere, asthenosphere, mesosphere (also known as the lower mantle), outer core, and inner core. These layers vary in composition, temperature, and physical properties, playing distinct roles in the Earth's structure and dynamics.

Layers of the athmosphere?
The Earth's atmosphere is divided into five layers: the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. Each layer has its own unique characteristics based on temperature, composition, and physical properties. These layers work together to protect life on Earth by regulating temperature and filtering harmful radiation.
