Answer:

The geothermal gradient is 25c for every 1k of depth below Earth's surface

Answer:

Gradient

Explanation:

  • There is an increase in the internal temperature of the earth with an increase in the depth from the surface.
  • The average geothermal gradient near the surface is about 25 degrees centigrade for every one kilometer of depth.
  • In some areas there is a much higher heat flows because of the presence of deep fault zones, rifting, magmatic intrusions, or active tectonic forces.
  • Conditions in the deep mines can be quite uncomfortable and hot enough to explode rocks or bend steel due to the presence of geothermal gradient.
