1. Crust: The outermost layer, with temperatures ranging from near-freezing at the surface to around 932°F (500°C) at its base.
2. Mantle: The thickest layer, extending from the crust to the outer core. Temperatures increase with depth, reaching about 4,000°F (2,200°C) at the top of the outer core.
3. Outer Core: A liquid layer of iron and nickel, with temperatures ranging from 4,000°F (2,200°C) to 9,392°F (5,200°C).
4. Inner Core: A solid sphere of iron and nickel, with temperatures reaching an astounding 9,700°F (5,400°C) or even higher.
Note: The exact temperatures within the Earth are difficult to measure directly, so these are estimates based on scientific observations and modeling.
