Final answer:
The pressure from the crust, mantle, and outer core makes Earth's inner core solid.
Step-by-step explanation:
The correct statement about Earth's interior is C - The pressure from the crust, mantle, and outer core makes Earth's inner core solid.
Earth's interior is composed of several layers, including the crust, mantle, outer core, and inner core. The inner core is under immense pressure from the layers above, which causes it to remain solid despite its extremely high temperatures. This pressure prevents it from melting into a liquid state.
Understanding the composition and characteristics of Earth's interior is crucial in studying geology and the processes that shape our planet.
