The characteristic of the outer core that makes it different from the other layers of Earth is:
**c. The outer core is liquid due to intense heat.**
The outer core is primarily composed of molten metal (mainly iron and nickel), which distinguishes it from the solid inner core, the semi-solid mantle, and the crust.
