What is core-mantle-crust?

The Earth is divided into three main layers: the core (innermost layer composed mostly of iron and nickel), the mantle (middle layer made up of solid and molten rock), and the crust (outermost layer of solid rock that forms the Earth's surface). Each layer has distinct properties and composition that contribute to the planet's structure and dynamics.
