An unusual layer has been found in the Earth's mantle. Turns out he's sticky.

Most of the planet's mantle is hot but solid. But a new study has found that about 150 km

there is a layer below the surface of the Earthmolten rock. It is found in the asthenosphere, the upper layer of the mantle, which is located between 80 km and 200 km below the Earth's surface. The only way to "look" there is to study seismic waves from earthquakes.

So, based on the latest data,The researchers hypothesized that some parts of the asthenosphere were hotter than others. They also found patchy regions of melt, but they didn't know how deep or widespread these melt regions were.

As part of the new study, scientists collecteddata from thousands of seismic waves detected at 716 stations around the world. They found that the asthenosphere contains a partially molten layer that extends under at least 44% of the planet. However, it could be much larger because scientists have not been able to probe the ocean floor. It likely covers a layer of melt that covers a much larger area than the continents.

Oddly enough, this molten layer does not affect the movement of tectonic plates or the viscosity of the mantle.
