The composition of the core is probably similar throughout. Why, then, is part of the core liquid and the rest solid?
Homework
Study words of the week.

2. Answer
The inner core is extremely hot but the high pressure keeps the material in a solid state. The outer core has less pressure so the iron can stay in a liquid state.

3. Did you know…?
The deepest hole ever drilled was 12,226 feet deep. It was difficult to drill deeper because liquid rock filled the hole.
