Which layer of Earth is composed primarily of iron and nickel? (a) The core, (b) The crust, (c) The asthenophere, (d) The mantle, (e) The lithosphere.

The layer of the Earth that is composed primarily of iron and nickel is (a) the core. Therefore the correct option is option A.

The Earth's core is separated into two parts: a solid inner core and a liquid outer core. Both the inner and outer cores are primarily made of iron and nickel, with trace amounts of sulphur and oxygen. The core is the densest layer of the Earth and is assumed to have an important part in the generation of the planet's magnetic field.

The Earth is made up several strata, each with its own distinct traits and composition.

The crust is the Earth's outermost layer and the thinnest of all the layers.

Mantle: The mantle is the layer under the crust that reaches to a depth of around 2,900 km.

The core is the Earth's innermost layer, and it is mostly composed of iron and nickel.
