It was observed that p (pressure) waves from earthquakes passed through the core bus s (sheer) waves from earthquakes did not.
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 layers 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.
Yes, it is worthy to study minerals becasue minerals provide many facts. Some aspects of minerals, such as their outer layer can tell us how old they are. Other rocks can be studied. Who knows, you might discover a new mineral!!
Neptune is an outer planet. It is the outermost planet in the solar system.
No, sally did not discover anything in outer space.
It was made to discover the secrets of outer space.
Alan Shepard was the first and second American to go to outer space.
Boop he went under ground
He's a mechanical engineer at Cal Tech, specializaing in gear used in outer space.

Alan Shepard
Telescopes have helped discover many things in space that are not visible such as some of the outer planets of our solar system.

Happy Birthday
Alan sheperd was the first astronaut in space.
