Detailed explanation-1: -The inner core experiences the highest pressure.
Detailed explanation-2: -Pressure and gravity The pressure in the Earth’s inner core is slightly higher than it is at the boundary between the outer and inner cores: It ranges from about 330 to 360 gigapascals (3, 300, 000 to 3, 600, 000 atm).
Detailed explanation-3: -The interior of Earth is very hot (the temperature of the core reaches more than 5, 000 degrees Celsius) for two main reasons: The heat from when the planet formed, The heat from the decay of radioactive elements.
Detailed explanation-4: -The inner core is indeed hotter than the outer core. However, the PRESSURE on the inner core is greater than the pressure on the outer core and the melting point of iron, the main constituent of the core, INCREASES as the pressure goes up.
