This is the third module in a series of four covering scales from ‘Atoms to Molecules’, through ‘The Cell’ and ‘The Earth’ to ‘The Universe’. This module focuses on the physical, chemical and biological processes that have shaped the development of the Earth. The module takes a systems approach in order to understand the interconnectivity between the various components of the Earth system, i.e. the atmosphere, biosphere, hydrosphere and lithosphere. Using this approach, students will study the impact that anthropogenic activities, such as burning fossil fuels, has had on the Earth system.
