Question:
Which of the following correctly describes the composition of Earth’s core?
Which of the following correctly describes the composition of Earth’s core?
Show Hint
The outer core is liquid and the inner core is solid—both made mostly of iron and nickel.
Updated On: Jun 16, 2025
- Silicate rocks with low-density elements
- Solid iron-nickel outer core and liquid silicate inner core
- Liquid iron-nickel outer core and solid iron-nickel inner core
- Primarily aluminum silicate with traces of magnesium
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Earth’s core is differentiated into two parts: a liquid outer core composed of molten iron and nickel, and a solid inner core made primarily of solid iron and nickel. This structure has been inferred from seismic wave behavior and is key to understanding Earth's magnetic field.
