Geology and geography are demanding subjects, which are highly relevant for understanding today's world. Knowledge of natural processes is needed as never before. We humans also greatly need to find ways of improving our record in environmental matters. Globalisation of economy and culture is also rapidly changing the position of regions and places within an interconnected world, which calls for academic understanding. Geology is concerned with the Earth itself, its formation and constant remaking.
Geologists seek an understanding of the nature and speed of the processes involved.
They look at connections between past and present processes and try to find out what the future might entail, for example in the case of global climatic changes. Lately geologists have also contributed to efforts at protecting the Earth against human-induced damages, and to present its wonders to nature observers and tourists. In Iceland, geologists are involved in research at various institutions as well as in various practical tasks for local governments and private companies. Geography is concerned with human existence in nature, as well as many other aspects of human society. Physical geography deals with processes on the Earth's surface, for example geomorphic processes, soil formation and erosion, vegetation and climate.
