Question

The Earth's inner core is in a state, while the outer core is in a state.

• A. solid
• B. liquid
• C. gaseous
• D. semi-gaseous

Answer 1

Answer: (A), (B)

The correct options are
A solid
B liquid

The inner core is hotter than the outer core. However, in the outer core, the heat melts the core despite the amount of pressure present. In the case of the inner core, the effect of the pressure trumps the effect of heat and holds the core's particles close together to form a tough solid.
