Final Exam #1

The sudden dip in the graph was because of the 9/11 terrorist attacks in 2001 because after that event, there were less and less oversea arrivals coming to the U.S.  since planes were not allowed to fly into the United States. Statistics can help explain historical events because if a number went down in the graph, you would know that some historical event influenced that drop in the graph. Or if something increased dramatically on the graph, we know that a past historical event caused that increase on the graph. So statistics can help human geographers know what past events happened to influence the statistics. One example that we discussed in class is when CO2 emissions went up in Trinidad and Tobago, the oil rise in that country led to the increase of more CO2 emissions .
