WebIn volcanic areas, the geothermal gradient is more like 40° to 50°C per kilometre, so the temperature at a 10 kilometre depth is in the 400° to 500°C range. Along subduction zones, as described above, the cold oceanic crust keeps temperatures low, so the gradient is typically less than 10°C per kilometre. WebGeothermal gradient measurements are made at specific locations. Temperatures must vary smoothly, however, so there is an expectation that geothermal gradients will vary smoothly between measurements. Inevitably there are insufficient measurements to characterize all variations and details in temperature and geothermal gradient. Any … michiel servaes twitter https://search-first-group.com
