04. Are these resources unique to space or can we also find them on Earth? (A K2S Question)

From The Space Library

Some of the elements, such as helium-3, are not found in massive quantities as they are in space, because the Earth is protected from the solar winds by the atmosphere and magnetosphere that surrounds it. Most of the elements are here on Earth, but are in different quantities or qualities due to the difference in compositional makeup of the various planets or celestial bodies, be they gaseous or terrestrial.
