Earth's Hot Inner Layers
The inner core of the Earth, a solid sphere of iron and nickel, reaches temperatures comparable to the sun's surface, driven by residual heat and radioactive decay. Surrounding it, the fluid outer core plays a crucial role in generating Earth's magnetic field. The complexity of the mantle's structure arises from differing classifications based on chemical composition and mechanical behavior, highlighting the intricate nature of Earth's internal layers.In this clip
