Credit Hours: 3.00. This course provides an overview of the processes controlling the distribution of elements within the earth’s lithosphere, hydrosphere, atmosphere, and biosphere. The two lecture hours per week stress how elements’ distributions within our planet are dictated by periodicity and affinity for reactions. These lectures are supplemented by a 3-hour problem-solving session used for discussion of quantitative problems assigned as homework. Prior course work in second semester chemistry and second semester physics is required. Typically offered Fall Spring.
