Geothermal gradient is the rate of increasing temperature with respect to an increasing depth in the Earth's interior. It is approximately 25 degrees Celsius per kilometer of depth.
North Carolina has an intermediate geothermal gradient!
Varies obviously, but the average geothermal gradient in the Earth's continental crust is 25 degrees Centigrade/kilometre

This is called the "geothermal gradient".

geothermal starts at the outer edge of the earth's crust and gets hotter the deeper you go. The gradual increase in the temperature as the depth increases is called the geothermal gradient. As you proceed through the crust the gradient is gradual. When you break through the upper mantle the temps then rise almost exponentially.
It is called the geothermal gradient, which means that the closer to the mantel or core (underground) you go, the hotter it gets.

The geothermal gradient is caused by the heat emanating from Earth's interior. It increases as you go deeper into the Earth's crust and upper mantle due to the combination of radioactive decay of elements, residual heat from planetary formation, and the insulating effect of Earth's layers trapping heat.
The temperature increases. The average geothermal gradient is 25C/Km
The soil temperatre increases as depth increases due to the heat created by the compression of the surrounding earth. The rate of change of temperature with depth is referred to as the geothermal gradient. The geothermal gradient varies depending on location, so there is no uniform answer. On average, the geothermal gradient is approximately 75 degrees F per mile. In volcanically active areas, the gradient can be as high as 150 degrees F per mile. In ocean trenches, the gradient may be as low as 15 degrees F per mile. Decay of naturally occurring radioactive elements may also cause localized increases in temperature in some locations.
