WebAs upwelling of magma continues, the plates continue to diverge, a process known as seafloor spreading. Samples collected from the ocean floor show that the age of oceanic crust increases with distance from the spreading … WebSo far, it is over 36,000 feet deep as far as scientists have been able to track. Of course, it could be even deeper; researchers and explorers haven’t yet traversed the entire trench. …

What is the deepest we have ever gone into the Earth?

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… Web21 okt. 2024 · The World’s Deepest Drillings The Earth’s crust averages about 18 miles in thickness under the continents but can be as thin as 3 miles beneath the oceans.
