Regarding the Earth's core, which is a place of very high temperatures due to the concentration of high-density material, composed mainly of nickel and iron, and which remains solid due to the high pressure on that point, analyze the following statements:

The Earth's core is divided into two parts, the outer core and the inner core. The inner core is dense and solid, while the outer core surrounds the inner core with a liquid layer.
Due to the high temperature, the inner part of the Earth (the core) melts, forming only a large liquid core.
Scientific studies allow us to understand that the layers of the Earth towards its interior are influenced both by the inner core and external pressure, which is why they present different formations.
The outer part that surrounds the core is fluid, presenting less density, it is an igneous rock rich in iron and magnesium, still hot and fluid.
