Scientists discovered that the inner core of Earth is a solid. Explain what evidence supports this thinking. Be sure to include how pressure, temperature, and density play a role
The inner core is solid because the inner core consists of a lot of pressure and high temperatures. And the more pressure and high temperatures the more dense the substance gets.
The inner core is solid because the inner core consists of a lot of pressure/high temperatures. (The more pressure and high temperatures, the denser the substance gets.)
