The outer core of the Earth is the layer that contains molten iron and nickel.
Earth's Layers and Their Composition
Understanding the Earth's structure helps clarify where molten iron is located. The Earth is composed of several layers, each with distinct characteristics:
- Crust: The outermost solid layer, composed of rocks and minerals.
- Mantle: A thick, mostly solid layer beneath the crust.
- Outer Core: A liquid layer made up primarily of molten iron and nickel, surrounding the inner core. This is where the melted iron is found.
- Inner Core: A solid sphere of iron and nickel at the Earth's center.
The Outer Core: A Sea of Molten Metal
The reference states that the outer core is "the layer of molten iron and nickel that surrounds the inner core." This layer is crucial for generating Earth's magnetic field. The movement of the liquid metal within the outer core creates electric currents, which in turn generate the magnetic field that protects our planet from harmful solar radiation.
Key Takeaway
The outer core is the specific layer of the Earth that contains melted iron.
