This module provides an introduction to environmental processes and their impacts in a variety of different environments. We discuss the physical processes governing the Earth's global climate system and their influence on recent and future patterns of climate and environmental change. We investigate the Earth’s surface materials and the laws that govern the behaviour of fluids, and how these affect environmental flow and fluid transport processes. We also explore the processes which influence the development of soils and associated ecosystems at the land surface, including deposition and erosion processes.
