Web9 mrt. 2024 · Long answer: Our deepest drills failed around 12km down when the drill bits were having to cope with temperatures hot enough to melt the drills. 12km down is only a tiny distance into the earth. The average distance to the center is over 6300km. So didn't even get to half of a percent of the way to the center. To do so, we'd have to have: Webthe upper mantle. As we read before, crust can be divided into two different types, continental and oceanic crust. Both types “float” on the denser mantle. Continental crust is about 25-90 km (15-55 mi) thick and divided into tectonic plates. These plates move slowly (just a few centimeters) each year over the more fluid mantle.

Web19 dec. 2012 · Now, models for the geothermal gradient (how hot it gets with depth; see above) on Earth as you go down through the crust into the upper mantle pegs the temperature at 200 km at somewhere between ... Geothermal 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 from tectonic plate boundaries, temperature rises in about 25–30 °C/km (72–87 °F/mi) of depth near the surface in most of the world. However, in some cases the tem…
