The core is found about 2,900 kilometers (1,802 miles) below Earth’s surface, and has a radius of about 3,485 kilometers (2,165 miles). Planet Earth is older than the core. When Earth was formed about 4.5 billion years ago, it was a uniform ball of hot rock. maxi clean prospect heightsWebPressure also prevents Earth outer core from losing heat. Of course a part of Earth's outer core is solidifying. Lighter elements are solidifying on the surface of the outer core as the outer core loses heat to the mantle. This causes dynamical patterns and is one reason for why the Earth has a magnetic field. maxi clear tabletsEarth's mantle is a layer of silicate rock between the crust and the outer core.
