Question

Why is the earth 's interior in most part found in a solid state despite great heat and pressure

Answer 1

Great pressure is what causes the core to behave like a solid rather than liquid. Due to the immense pressure of the upper layers of earth on core, the pressure can reach as high as thousands and thousands of tone's per square inch!!!! So this would not come to you as a shock if a semi liquid starts to behave like a solid in these conditions

Answer 2

The earth’s inner core has a radius of about 1,220 kilometres. Its composition is mainly iron-nickel alloy and other elements. It is basically a solid ball. The temperature of the core is 6,000 degrees Celsius, almost as hot as the Sun.

 

Even though the temperature of the earth’s core is very high, the extreme pressure in the core keeps the iron-nickel compound solid.
