Identify the four spheres of the biophysical environment and briefly describe each. Explain the processes that occur within one of these spheres and analyse the ways that humans interact with that sphere at a variety of scales. 

Using examples, explain the concept of sustainable development and outline sustainable development strategies and practices. 

Describe a case study of ONE issue in ONE of the biophysical components and explain how an understanding of biophysical processes contributes to sustainable management of the environment.

Write a report describing each layer of the biophysical environment.

Using case studies, describe how each of the four spheres of the biophysical environment can be affected by the activities of humans.
