50 points + brainliest scientists discovered that the inner core is a solid. explain what evidence supports this thinking. be sure to include how pressure, temperature, and density play a role.

The Earth's inner core is the Earth's innermost part. It is primarily a solid ball with a radius of about 1,220 km (760 miles), which is about 70% of the Moon's radius.[1][2] It is composed of an iron–nickel alloy and some light elements. The temperature at the inner core's surface is approximately 5,700 K (5,430 °C), which is about the temperature at the surface of the Sun. 

Hope this helps and good luck :)

The pressure of the rest of the world makes the core solid. It also makes the melting point go up.
