Q: Approximately what is the normal rate of temperature rise with depth from the surface of the Earth to the interior of the Earth?
  • A. 1⁰C per 185 meter
  • B. 1⁰C per 185 feet
  • C. 1⁰C per 32 meter
  • D. 1⁰C per 32 feet
Correct Answer: Option C - The geothermal gradient (i.e. the increase in temperature with an increase in depth in the Earth) is not equal all over the world. On average the rate of temperature rise with the depth from the surface of the interior of the earth is 1° C per 32 meter.
C. The geothermal gradient (i.e. the increase in temperature with an increase in depth in the Earth) is not equal all over the world. On average the rate of temperature rise with the depth from the surface of the interior of the earth is 1° C per 32 meter.
