Hi, Questions:
1) If both the Sun and the planets formed from the same gas/dust cloud, how come the Sun is mostly Hydrogen and the Earth is a rocky planet? 2) If some selection process caused primarily Hydrogen to condense at the middle, why are the rocky planets closer to the Sun than the gas giants? Regards, R. van Spaandonk Crops, not towns, should be planted on floodplains. Even the ancient Egyptians knew this.
