》Planetary differentiation《
In planetary science, planetary differentiation is the process of separating out the different components within a planetary body as a consequence of their physical or chemical behavior (e.g. density and chemical affinities). The process of planetary differentiation is mediated by partial melting with heat from radioactive isotope decay and planetary accretion. Planetary differentiation has occurred on planets, dwarf planets, the asteroid 4 Vesta, and natural satellites (such as the Moon).
A permeable rock breaks down quicker than a rock that is not so permeable because there is less space for anything (i.e. water) to get in the not so permeable rock in order to widen the holes and ultimately break the rock. On the other hand, a permeable rock is full of holes and will break down because of the many holes available to widen.
