WebThe two largest planets, Jupiter and Saturn, have nearly the same chemical makeup as the Sun; they are composed primarily of the two elements hydrogen and helium, with 75% of their mass being hydrogen and 25% helium. On Earth, both hydrogen and helium are gases, so Jupiter and Saturn are sometimes called gas planets. But, this name is misleading. Web12.7 The structure of the earth is divided into four major layers which is purely based on chemical composition and physical characteristics. These layers include the crust, the mantle, the outer core, and the inner core. The crust is the outermost layer where humans reside on. It is usually categorized into two groups: the continental crust which is …
