The geothermal gradient
WebThe Geothermal Gradient. As heat wells up from the interior of the Earth, the temperatures must increase with depth. This rate of heat flow with depth is the Geothermal Gradient. It is usually calculated from measurements in mines and drill holes and ranges from 8° C / km up to 65° C / km but average some 35° C / km in continental crust. WebGeothermal gradients from published temperature/depth measurements in drill holes generally deeper than 600 m are used to construct a temperature gradient map of the conterminuous United States. The broadly contoured map displays 284 temperature gradients that are applicable to a depth of 2 km.

Convection Helps to Move Heat Within Earth. The fact that the temperature gradient is much lower in the main part of the mantle than in the lithosphere has been interpreted as evidence of convection in the mantle. When ...
Web8 Sep 2024 · The geothermal gradient of the entire hole is greater than 20°C per 100 m, which is located at the connection of boreholes ZK16, ZK15, ZK21, and ZK19. 4.1.3. Spatial Distribution Characteristics of Geothermal Field Figure 6 shows the isotherms of +300 m, +200 m, +100 m, and ±0 m above sea level. WebThe red line on the graph is the geothermal gradient which shows the rate of increasing temperature with respect to increase with depth into the Earth’s interior. On average (i.e. away from plate boundaries and hotspots) temperature increases at a rate of 25-30°C per km in the lithosphere. The
