The goal of this course is to apply chemical principles to understand the natural (non-living) world around us and appreciate its complexity.
The chemical principles usually covered in general chemistry, undergraduate inorganic chemistry, and physical chemistry enable us to examine many aspects of the Earth. We will look at the formation of the elements, and describe the reason for the different abundances, and what this means for the Earth’s composition. We will also look at how isotopes can be used as chemical tracers and “clocks”, leading us to insight on the various processes of the Earth, and even our own bodies. Finally, we will see how geochemistry can help us understand, or even combat the many environmental and technological problems that we face.
What you’ll learn:
- How the Earth’s elements are formed
- What determines the elements’ abundances and distribution on Earth
- How can we identify the climate millions of years ago
- How to use isotopes to identify what we eat
- How can we classify something as general as “rocks”, and explain the diversity
- How geochemistry can help be applied to solve environmental/technological problems
