Willing to give brainliest. scientists have discovered that the inner core of earth is a solid while the outer core is a liquid. what is the cause of this observation? a. the outer core has a higher temperature and more pressure than the inner core b. the outer core has a lower temperature and lower pressure than the inner core c. the inner core has a lower temperature and higher pressure than the outer core d. the inner core has a higher temperature and lower pressure than the outer core

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.
