Review of the Occurrence and Cycling of the Elements in Nature

Most of the elements that are known today are naturally occurring elements. When we talk about elements and their presence on earth the first question that arises in mind is regarding the distribution of these elements on earth. The scientific discovery tells us that the center part of the earth is comprised of a solid core that is mainly comprised of Iron. There is a hot fluid present in mantle which is a layer in the surrounding of the core. This hot fluid comprises of iron, carbon, silicon, sulfur. Out of the 83 elements, there are 12 elements that make up the 99.7 percent of the crust of earth by mass. If we consider the percentage of mass in the constitution of earth's crust then it would be revealed to us that oxygen is an element that is present in higher percentage than any other element. The element that is present in less percentage is manganese. While discussing the occurrence of elements in nature it should be kept in mind that all the elements are not evenly distributed in the earth. Most of the elements occur in the combined form. These elements are also present in the human body. The constituent of different elements in human body can be described in the form of following chart (Nina, 2005):
