D. The inner core has a higher temperature and lower pressure than the outer core.
Explanation:
Contrary to popular belief, the inner core of the earth is solid, consisting primarily of nickel and iron. Therefore, evidence points to the center of the earth being a large iron ball surrounded by a layer of liquid rocks.
The inner core of the earth is solid because the force of the pressure is so overwhelming that its effects overlap with temperatures, preventing the molecules from remaining in a state of agitation. This high pressure contributed to the recording of thermal averages similar to those in the sun. For this reason, we can say that the inner core has higher temperature and pressure than the outer core.
B. the inner core has a higher temp than the outer core and the pressure is greater for the inner core witch makes it a solid. I'm not the smartest bean out there but I hoped this helped
