Oxygen accounts for nearly half of the mass of the earth's crust, two thirds of the mass of the human body and nine tenths of the mass of water. Spectrum B shows the same element as seen in the light from a distant star. All animals and many microorganisms need oxygen to fuel their growth (and metabolism). It is divided into four layers: the troposphere, stratosphere, mesosphere and thermosphere. Sometimes fires burn down large areas of forests that are part of the biosphere. All of the other elements are relatively rare. The early Greeks considered "air" to be one of four elementary substances; along with earth, fire, and water, air was viewed as a fundamental component of the universe.By the early 1800s, however, scientists such as John Dalton recognized that the atmosphere was in fact composed of several chemically distinct gases, … Beyond Earth the most common element is hydrogen.
