The atmosphere of terrestrial planets, such as Earth and Mars, is generally thin and composed mainly of rock and metal, with gases like oxygen, carbon dioxide, and nitrogen. In contrast, gas giants like Jupiter and Saturn have thick atmospheres primarily made of hydrogen and helium, along with trace amounts of other gases like methane and ammonia. While terrestrial planets have solid surfaces, gas giants lack a well-defined surface and possess deep atmospheres with complex weather systems and strong winds. This fundamental difference in composition and structure leads to distinct environmental conditions on each type of planet.

Compare gas giants to terrestrial planets?

Gas giants are composed mostly of gases like hydrogen and helium, while terrestrial planets are predominantly composed of solid materials like rock and metal. Gas giants have thick atmospheres and lack solid surfaces, whereas terrestrial planets have solid surfaces that can support geological activity. Gas giants are much larger in size compared to terrestrial planets.
