name the layers of the core in liquid and solid state
Answers
Answer:
I hope this answer will help u...
Explanation:
The inner core is solid, the outer core is liquid, and the mantle is solid/plastic. This is due to the relative melting points of the different layers (nickel–iron core, silicate crust and mantle) and the increase in temperature and pressure as depth increases
Answer:
The inner core is solid due to the massive pressure on it. Scientists theorize that the heat of the solid inner core is keeping the outer core in a semi-liquid state which allows the inner core to spin at a slightly different rate than the rest of the earth. This gives the earth its magnetic poles which diverts damaging cosmic rays from colliding with earth. The theories are the result of measurements during volcanic activity and sound waves.
The mantle is a plastic solid of varying densities which allow convection currents to flow molten rock towards the earth's surface resulting in volcanic activity, tectonic plate movement, earthquakes, and movement of continents.
