Here's a breakdown of Earth's layers by chemical composition:
* Crust: The outermost layer, relatively thin and composed primarily of lighter elements like silicon, oxygen, aluminum, and iron.
* Mantle: The thickest layer, extending from the crust to the outer core. It is mainly composed of silicate minerals rich in iron and magnesium.
* Core: The innermost layer, divided into the liquid outer core and solid inner core. It is primarily composed of iron and nickel, with trace amounts of other elements.
