The statement that temperatures and pressures are higher in the inner core than in the outer core is true. The core is divided into two parts - the inner core and the outer core. The inner core is solid and mostly composed of iron and nickel, whereas the outer core is liquid. The temperatures in the outer core reach several thousand degrees, and the pressures at the center of the Earth are over 3 million times atmospheric pressure.
