The temperature of Earth’s outer core is estimated to range between approximately 4,000 to 6,000 degrees Celsius (7,200 to 10,800 degrees Fahrenheit).
This extreme heat comes from several sources, including the decay of radioactive isotopes and residual heat from the planet’s formation. The outer core is composed mainly of liquid iron and nickel, and this high temperature keeps the metals in a molten state.
The movement of these molten metals is also responsible for generating Earth’s magnetic field through a process known as the geodynamo. Understanding the temperature of the outer core is crucial for geologists and seismologists as it helps in deciphering the Earth’s interior structure and behavior.
