Determine the temperature in the mine at a depth of 1200 m if the surface temperature is 0 ° C.

The geothermal gradient (Δt) of the earth’s crust is 3o for every 100 m.
Let’s determine the temperature in the mine:
1200 m: 100 m × 3 ° C = 36 ° C
Answer: Temperature in a mine at a depth of 1200 m = 36 ° C
