Module question

3. Which are the main geological processes of the so-called rock cycle? How do these combine with the weathering and erosion of rocks to explain e.g. the formation of deposits of ores and fossil hydro-carbons such as oil and gas? Module question 4. What different forms of biodiversity are there? Give some northern examples! How is the biodiversity of sub-Arctic and Arctic ecosystems influenced by the fact that they often have small number of species?

Module question 7

. To what extent will the climate change presently reported by scientific communities bring about transitions in nature and human societies – globally and in the Arctic? What about turning the question around: can socio-political and economic change stop global warming? Module question 9. Present some dilemmas of combining scientific nature management with traditional and modernized rural life up north! What does Igor Krupnik mean when he states that “not all polar bears are born equal”?
