Question

What is the difference between the inner and outer core of the Earth? A) The inner core is liquid and the outer core is solid. B) The inner core is made from magma and the outer core is metal. C) The inner core is solid and the outer core is liquid. D) The inner core is cool and the outer core is hot. E) The inner core is hot and the outer core is cool.

Answer 1

The inner core of the Earth is solid and made largely of iron and nickel, whereas the outer core is liquid, composed of similar material but in a melted state due to high temperatures and pressure. The correct answer is C) The inner core is solid and the outer core is liquid.

Step-by-step explanation:

The difference between the inner and outer core of the Earth lies in their states of matter and composition. The inner core is solid and composed largely of iron and some nickel. In contrast, the outer core, which surrounds the inner core, is in a liquid state and also consists mainly of iron and nickel. The outer core is not solid because it is subject to extremely high temperatures and pressures which melt the iron-nickel alloy.
