Whatâs Eating You? Chronic stomach pain isnât fun â I used to be a chronic overeater, and it was tough to teach myself to put the fork down when I started to feel full. Once I got a handle on my overeating, I still suffered from stomach pain.
A layer of the upper mantle that flows due to heat currents moving through solid rock. Outer Core. the liquid layer made up of hot liquid iron and nickel that surrounds the inner core. Inner Core. a dense ball of solid metal that is the hottest and densest layer of the Earth.
The inner core is solid, the outer core is liquid, and the mantle solid/plastic. This is because of the relative melting points of the different layers (nickelâiron core, silicate crust and mantle) and the increase in temperature and pressure as depth increases.he inner core is solid, the outer core is liquid, and the mantle solid/plastic.
