Which elements are abundant in the formation of interior layer of the ...
Key Points
- Core, mantle and crust are the three main concentric layers of the earth’s interior.
- The core is the innermost layer and has the highest density. It is made up mainly of nickel and iron.
- The core is the densest layer of the earth with its density ranging from 9.5 to 14.5 and sometimes even higher. It is composed mainly of iron and nickel thus commonly known as Nife (Nickel+Ferrum).
- The core consists of two sub-layers. The inner one is solid and the outer one is semi-liquid
- The mantle is the layer lying between the core and lithosphere and is about 2900 km thick. Its major constituents are silicon and magnesium. The density of this layer varies from 3.3 to 5.7.
- The mantle is surrounded by the outermost layer of the earth, known as the lithosphere and its density varies from 2.70 to 2.95.
- Major constituent elements of the lithosphere are silica (Si) and aluminium (Al), thus this layer is termed Sial (Silica+Aluminium).
- The outermost part of the lithosphere in known as the crust, normally about 8 to 40 km thick.

Which elements are abundant in the formation of interior layer of the ...
Main Elements in the Formation of Nife:
- Nickel and Iron (Nife): The interior layer of the Earth, also known as the core, is primarily composed of Nickel and Iron (Nife). These elements are abundant in this layer and play a crucial role in the Earth's structure and composition.
Explanation:
- The core is divided into two parts: the outer core and the inner core. The outer core is primarily composed of liquid iron and nickel, while the inner core is believed to be a solid ball of iron and nickel alloy.
- Nickel and iron are dense elements, which contribute to the overall density of the Earth's core. This density is essential for understanding the Earth's gravitational pull and its magnetic field.
- The presence of nickel and iron in the core also helps explain the Earth's internal heat distribution and the generation of the planet's magnetic field. The movement of liquid iron in the outer core creates convection currents, which generate the Earth's magnetic field.
- Overall, the abundance of Nickel and Iron (Nife) in the formation of the Earth's interior layer is crucial for understanding the planet's structure, composition, and geophysical processes.
