There is a fourth year undergrad course about cold region and Arctic. The writer need to have a geology background. There are three papers attached below need to be read and answer the questions. Please note that there is NO outside source can be used, all the answers have to from that three papers. There is no strict word limit, as long as the questions are correctly answered should be fine. Also, I am a ESL student, please just make sure the questions are correctly answered but don’t use too much difficult sentence or fancy words. I attached one of the pervious assignment as an example to see my writing style (called assignment 5). Please use each question as the heading of each paragraph and answer the question in a paragraphy form.
