What resulted in the formation of three subterranean sections on early Earth?
What resulted in the formation of three subterranean sections on early Earth?
- Melting of iron and nickel
- Extraction of heavy metals
- Uniform composition and density
- Chemical differentiation (correct)
How did the formation of the Earth's layers occur?
How did the formation of the Earth's layers occur?
- Melting point of iron and nickel was reached, causing them to settle to Earth’s center
- Denser iron and nickel settled to the center while lighter silicates formed the mantle and crust (correct)
- Heavy metals were extracted from the Earth's interior and concentrated in the developing crust
- The ascending molten masses led to the formation of different layers
What contributed to the concentration of heavy metals in the developing crust?
