Question

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.

Answer 1

Discovery. Earth was discovered to have a solid inner core distinct from its molten outer core in 1936, by the Danish seismologist Inge Lehmann, who deduced its presence by studying seismograms from earthquakes in New Zealand.

Answer 2

Answer:

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. Therefore, what is making the inner core a solid is the high temperatures and the pressure that the inner core consists of because the more dense the substance the more solidified it is.
