It's because 3 if it was 10 it wouldn't look right do it goes up to 4d

Because they're in different places for this the temperature varies.

Year  1936,  lehman predicted that the earths 'inner core' is solid. she observed that the seismic signals during her study were bent and did not pass through instead bouncing back. later it was confirmed that the earth's inner core was solid made up of nickel-iron and had a molten outer core.

Well it depends on the object or substance
