Depth of geothermal lines
WebGeothermal gradient is the rate of temperature change with respect to increasing depth in Earth 's interior. As a general rule, the crust temperature rises with depth due to the heat flow from the much hotter mantle; away … WebTemperature increases with depth within the Earth at an average of about 25ºC/km. So if the average surface temperature is 20ºC, the temperature at 3 km is only 95ºC. Although …
