What is the correct order of Earth's zones from the center outward?

The correct order of Earth's zones from the center outward is inner core, outer core, mantle, crust.

The inner core is the very center of the Earth, composed primarily of solid iron and nickel, and is under immense pressure and temperature. Surrounding the inner core is the outer core, which is in a liquid state and also consists mainly of iron and nickel. The movement of the liquid outer core generates Earth's magnetic field.

Next is the mantle, which is much thicker than the core and is composed of semi-solid rock that flows slowly over geological time. This layer plays a crucial role in tectonic plate movements due to its convective currents. Finally, the crust is the outermost layer of the Earth, consisting of solid rock and soil where we live. It is relatively thin compared to the layers beneath it.

Understanding this order is essential for grasping concepts related to geology, plate tectonics, and Earth's structure as a whole.
