How did Beno Gutenberg discover the boundary between mantle and outer core?
He didnt just discover 'a boundary' between mantle and outer core. He provided the first reasonable accounting of Earths interior (proved the thought that the earth was in lay…ers and not just a homogenous planet). He was also the first to estimate the temperature and physical properties of the earths core, which is why the boundary is called after him. He first discovered the layers through seismic waves from earthquakes, realising they had different magnitudes and intensity because they must have had to go through layers before reaching the surface as well as depending where the epicentre is.
