Final answer:

The Earth's layers comprise the crust, mantle, and core, each with unique features based on chemical composition and physical attributes.


Explanation:

The Earth's layers consist of the crust, mantle, and core, each with distinct characteristics based on their chemical composition and physical properties.

The crust is the outermost layer, primarily composed of silicon, oxygen, aluminum, iron, and magnesium. Oceanic crust is denser and thinner than continental crust.

Beneath the crust lies the mantle, which includes both rigid and molten layers responsible for movements like mantle convection.
