In the mantle,
temperatures range between 500 to 900 °C (932 to 1,652 °F) at the
upper boundary with the crust to over 4,000 °C (7,230 °F) at the
boundary with the core. Although the higher temperatures far exceed the melting points of the mantle rocks at the
surface (about 1200 °C for representative peridotite), … Read more
