Earth composition rocky or gas
WebDec 14, 2024 · The gas giants are made up mostly of hydrogen, methane and ammonia, all of which are very light in comparison to the rocky particles the inner planets collected. As these gases collected around a central point of gravity, the gas giants were formed. Is there a clear-cut difference between rocky and gaseous planets? WebThe four inner planets, those closest to the Sun, are Mercury, Venus, Earth, and Mars. They are smaller and composed mainly of metals and rocks. The four outer planets — Jupiter, Saturn, Uranus, and Neptune — are larger and composed mostly of gases. What are planets? Where did they come from? Why would some be rocky and some gaseous?
