Q: Geothermal gradient is defined as the increase in temperature with depth in the Earth. Accordingly, in normal continental crust the rate of temperature increase within the first 3 to 5 kilometers of the Earth’s surface is approximately………….
  • A. 25 °C/km
  • B. 70 °C/km
  • C. 40 °C/km
  • D. 10 °C/km
Correct Answer: Option A - Geothermal gradient is defined as the increase in temperature with depth in the Earth. Accordingly, in normal continental crust the rate of temperature increase within the first 3 to 5 kilometers of the Earth’s surface is approximately 25 °C/km. Geothermal gradient is the rate of increasing temperature with depth in the earth. It indicates heat flowing from the hot interiors Earth to its surface. ■ In normal continental crust, the first 3-5 km from the Earth’s surface. The rate of temperature rise within the region is about 25°C/km, it occurs.
