Earth’s core 1000 degrees hotter than thought
The temperature near the Earth’s centre is 6000 degrees Celsius, 1000 degrees hotter than last reported 20 years ago, scientists have found.
The core consists of a sphere of liquid iron at 4000 degrees. The temperature difference between the mantle and the core is the main driver of large-scale thermal movements, which together with the Earth’s rotation, act like a dynamo generating the Earth’s magnetic field. PTI
