37.A GIS is used to compare two satellite images of the same area taken ten years apart. What is the most likely reason for doing this?

38.Which of the following are consequences of using GIS to relate previously unrelated information through location? (Select all that apply.)

39.A GIS layer stores the location of a school using x = 14, y = 9 and z = 32. What does the z value represent?

40.A GIS contains a satellite image of a coastal town taken in 2005 and another taken in 2015. Which of the following statements about using these images are true? (Select all that apply.)
