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 care has lower temperature and lower pressure then 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.

Scientists figured out that the outer core must be liquid because S waves do not pass through it, but P waves do. The behavior of P and S waves also indicates that the inner core is solid. The speed of seismic waves also depends on the density of the material through which they are traveling.

the principles and empirical processes of discovery and demonstration considered characteristic of or necessary for scientific investigation, generally involving the observation of phenomena, the formulation of a hypothesis concerning the phenomena, experimentation to test the hypothesis, and development of a conclusion that confirms, rejects, or modifies the hypothesis.
