|Module Title||VOLCANIC ACTIVITY AND ENVIRONMENTAL CHANGE|
|Co-ordinator||Dr John Grattan|
|Course delivery||Lecture||22 Hours 11 x 2 hours|
|Assessment||Course work||Coursework to be submitted by the end of week 9.||50%|

2. Core concepts: Students will develop a clear theoretical and philosophical framework, which will allow them to assess the degree of inter relationship between different environmental systems. Central to this will be an understanding of the sensitivity of environmental systems to external forcing mechanisms.
