What is the Core?

What is the Core?

• A. The outermost shell of the Earth
• B. The hot gooey layer between crust and core
• C. The very center of the Earth made up of hot metals
• D. The solid layer surrounding the outer core

Answer: (C)

The core is the center of Earth, made mostly of hot metals such as iron and nickel. It has two parts: a solid inner core at the very center and a surrounding liquid outer core. This description fits best because it pins the core to the planet’s center and highlights its metallic composition. The crust is the outermost shell, and the layer between the crust and core is the mantle, which is not the core itself (and includes a solid portion surrounding the outer core). So, the core is defined by its central location and its metal content.
