Detailed explanation-1: -Humans have not been able to travel more than a few miles beneath Earth’s surface because of the intense heat and pressure. For the same reasons, humans have not been able to travel into the mantle. Temperatures in the mantle range from 1600 degrees Fahrenheit at the top to 4000 degrees Fahrenheit near the bottom.
Detailed explanation-2: -Short answer: No. On the large scale you can think of the Earth as a big ball of fluid. Withstanding the pressure of the bottom of the ocean is something that we are barely able to do, and that is only 0.2% of the way to the center of the Earth.
Detailed explanation-3: -No one has ever drilled into the mantle before, but there have been a half dozen serious attempts. Kola well’s derrick in 1980: still the world’s deepest hole.
Detailed explanation-4: -The temperature of the mantle varies greatly, from 1000°C (1832°F) near its boundary with the crust, to 3700°C (6692°F) near its boundary with the core. In the mantle, heat and pressure generally increase with depth. The geothermal gradient is a measurement of this increase.
