The Earth’s core is the innermost layer and the hottest part of the planet. It is primarily made of iron and nickel and is responsible for generating Earth’s magnetic field, which shields the planet from harmful solar radiation.
Structure
- Inner core – solid due to immense pressure
- Outer core – liquid and responsible for magnetic field generation
Key Functions
- Maintains Earth’s magnetic field
- Contributes to internal heat
- Supports plate tectonic activity indirectly
Examples
- Magnetic compass alignment
- Protection from solar winds
