- The Earth's outer core is composed mainly of liquid iron (85 %) and nickel (5 %) with the rest made up of a number of other elements
- The outer core is 2,260 km thick
- The outer core's upper boundary is 2,890 km below the surface
- The outer core's lower boundary is 5,150 km below the surface
- The temperature of the outer core varies from 4400 degrees C at it's upper boundary and 6100 degrees C at it's lower boundary
For more information about the outer core, please see the related question.
The depth is 2,250 kilometers. The Thickness is 2,300 kilometers. Composition is made of liquid nickel and iron. Temperature of the outer core is 2,200 Celsius.
The outer core of the Earth is a liquid layer composed mainly of iron and nickel. It surrounds the solid inner core and is responsible for generating the Earth's magnetic field through convection currents caused by the heat released from the inner core. The outer core is about 2,300 km thick and is located between the mantle and the inner core.

What are the physical properties of the outer core?
The outer core is a liquid layer composed mainly of iron and nickel. It is about 2,300 km thick and located between the Earth's mantle and inner core. The outer core is responsible for generating Earth's magnetic field through the movement of molten iron alloys.
Who discovered the Outer Core?
The outer core of the Earth was indirectly discovered by detecting seismic waves that travel through it. Scientists used data from earthquakes and seismic waves to infer the existence and properties of the outer core, which lies beneath the mantle.
What are the 5 structural zones of Earth?
The five structural zones of Earth are the inner core, outer core, mantle, asthenosphere, and lithosphere. Each zone has distinct physical and chemical properties that contribute to the structure and behavior of Earth's interior.
What are the earth's layers that are based on physical properties?
The Earth's layers based on physical properties are the lithosphere, asthenosphere, mesosphere, outer core, and inner core. The lithosphere is the rigid outer layer, the asthenosphere is a semi-fluid layer beneath the lithosphere, the mesosphere is a solid lower part of the mantle, the outer core is liquid iron and nickel layer, and the inner core is a solid iron-nickel alloy.
What does the outer core look like?
The outer core is a layer of the Earth that is predominantly composed of molten iron and nickel. It is located beneath the mantle and surrounds the solid inner core. Although it cannot be directly observed, scientists study the outer core's properties using seismic waves and other geophysical methods.
What is the liquid layer of the Earth's core called?
Based on the physical properties of the earth;The core is divided into outer core and inner core.the liquid layer of the earth core is the outer core,while the inner core is solid.
What are the physical properties of the outer core?
The outer core is a liquid layer composed mainly of iron and nickel. It is about 2,300 km thick and located between the Earth's mantle and inner core. The outer core is responsible for generating Earth's magnetic field through the movement of molten iron alloys.
What is the order of the earth's interior?
The Earth's interior has several layers in order from outer to inner: the crust, mantle, outer core, and inner core. These layers vary in composition, temperature, and physical properties.

What are the major layers of earths internal structure based on physical properties?
The major layers of Earth's internal structure based on physical properties are the inner core, outer core, mantle, and crust. The inner core is solid and composed mainly of iron and nickel. The outer core is liquid and also composed of iron and nickel. The mantle is a solid layer that lies between the core and the crust, and the crust is the outermost layer that we live on.
What are the earths layers of rock classified by?
The Earth's layers of rock are classified by their composition and physical properties. The main layers are the crust (continental and oceanic), mantle, and core (outer and inner). These layers are distinguished by differences in chemical composition, density, and temperature.
How does the outer core help the earth?
In more complex diagrams they show that we have an outer core. actually we do have but not for any chemical properties but for the slight difference in temperature. It helps in forming the magnetic sphere around us.
What are the earth's layers that are based on physical properties?

Although it cannot be directly observed, scientists study the outer core's properties using seismic waves and other geophysical methods.
What are the six layers of the earth?
The six layers of the Earth, from outermost to innermost, are the lithosphere, asthenosphere, mesosphere, outer core, inner core, and innermost core. Each layer has distinct physical and chemical properties that contribute to the Earth's structure and behavior.
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.
