The Earth's core is the innermost part of our planet, located beneath the mantle and crust.
--It is primarily composed of iron and nickel, with smaller amounts of other elements like sulfur and oxygen.
--The outer core is in a liquid state, while the inner core is solid due to the immense pressure at the center of the Earth.
--The temperature of the outer core is around 4,000 to 5,000 degrees Celsius, while the inner core can reach temperatures of up to 6,000 degrees Celsius.
--The Earth's magnetic field is generated by the movement of molten iron in the outer core, which creates electric currents that produce the magnetic field.
--The radius of the inner core is around 1,220 kilometers, while the radius of the outer core is about 3,400 kilometers.
--The mass of the Earth's core is estimated to be about one-third of the planet's total mass.
--Scientists study the Earth's core using seismic waves, which are waves of energy that travel through the Earth and can reveal information about the Earth's interior.
