Imagine other worlds where the entire planet is significantly volcanic. These types of events as depicted in the OP would be very commonplace in far
more extreme forms. We might call them primordial worlds, or even an old world that was obliterated in a cosmic collision and returned to a highly
Something I realized a long time ago is that like water, the materials that compose "rock" can also go through various states like ice, vapor, and
The carbon dioxide will eventually react with the porous rock and turn into a solid, carbonate compound, but that process can take
So even a gas can revert to a solid, though generally this is extremely slow.
Now imagine that, the surface of Earth is actually like standing on rock ice. It's frozen, usually. In the case of the lava in Hawaii, it's clearly
liquid in form. The temperatures for that are what we consider very high in order to melt these materials.
We even use the word "melt" with rocks turning into lava, just as we do with ice turning into liquid water. We also use the word "evaporate" to
describe the corresponding phenomena.
And here's a cool picture I found, it's an artists rendition of a moon around Jupiter (that almost certainly doesn't actually exist because Io isn't
likely to be anything like this at the surface level), but the concept is valid in terms of what "might exist and probably does exist" throughout the
Universe at large:
