Question: In The Upper 10 Km Of The Crust The Geothermal Gradient Is Typically About 25°C Per Km, But It Can Range From 15’C/km To 50°C/km. In The Chart Below.plot These Three Geothermal Gradients (15°C/km 25°C/km, And 50°C/kr) For The Upper 10 Km Of The Earth. Use One Line For Each Gradient 0 Green: Gradient 15 D C/km Yellow: Staden 1 2 Red: Gradient So …

In the upper 10 km of the crust the geothermal gradient is typically about 25°C per km, but it can range from 15’C/km to 50°C/km. In the chart below.plot these three geothermal gradients (15°C/km 25°C/km, and 50°C/kr) for the upper 10 km of the Earth.

Explain your answer. How hot is it in the bottom of this mine? What assumptions did you make to come up with this answer? n
