How hot is Earth's core?
Earth's core is estimated to be as hot as the surface of the sun, with temperatures ranging from 9,000 to over 10,000 degrees Fahrenheit. This heat is inferred through various scientific techniques, as direct measurement is not possible. The core is primarily composed of iron and nickel, with a liquid outer core and a solid inner core, and plays a crucial role in generating Earth's magnetic field.
- ▪Earth's core consists of a liquid outer core and a solid inner core.
- ▪The temperature of the Earth's core is estimated to be around 9,000 to just over 10,000 degrees Fahrenheit.
- ▪Scientists have inferred the core's temperature through experiments and theories about its composition.
