Astro-QA #8 : Why do the outer, gas-giant planets rotate faster than the inner, terrestrial planets?

To understand this, we need to think about how the planets formed. When the sun was formed and fusion started the lighter gas were swift far out in the solar system and heavier rockier material and metalics with high melting point stay closer to the Sun. Molten metal and dust particles stuck together to form rocks. Then gravity brings then together to form planets. So, in the hot inner region of the solar system the rocky planets with metal cores are ..
