Dynamic Planet Glaciers

Team Name+Number ________________________ Teammate 1 name _______________________ Teammate 2 name ________________________ Dynamic Planet: Glaciers The following test is 80 questions long, split up into four different sections. The first 20 questions are worth 40 total points and the following 60 questions are worth 60 total points, adding up to a grand total of 100 points. All questions are related to glaciers in one way or another, and each question can be easily found on the internet; there is no trickery here, just a test of how well you have done your research and how well you have prepared yourself for this event. The tiebreakers are as follows: 1st tiebreaker- Number of questions gotten right from Section C 2nd tiebreaker- Number of questions gotten right from Section A 3rd tiebreaker- Number of questions gotten right from Section B 4th tiebreaker- Number of questions gotten right from Section D There is an attached answer sheet that you may rip off. You have 50 minutes to complete this test and may use up to 4 double sided pages (8 ½” by 11”) worth of notes. Good Luck!
