| Dec 19, 2020 at 9:55 | comment | added | planetmaker | @PM2Ring You're right in your explanation. However often people mean the pressure inside the core when they say gravity; of course the pressure is a result of the gravity pressing the outer layers onto the core. | |
| Dec 19, 2020 at 9:49 | comment | added | James K | You seem to be asking "why do liquids and solids exist" I'm not sure that this is really a question of astronomy. I think "chemistry" might be a better place or perhaps Physics. The reason is that at low temperatures particles bond electromagnetically, | |
| Dec 19, 2020 at 7:58 | comment | added | PM 2Ring | 1 A small rock is held together by chemical forces (electromagnetism), not gravity. 2 "gravitational pull is stronger closer to the core" Not really. Inside a ball of uniform density, the gravity gets weaker as you approach the centre. See en.wikipedia.org/wiki/Shell_theorem | |
