Final answer:
Polar-orbiting satellites are useful for creating a time series loop of images for a specific location by capturing images of the same area at different times. These satellites orbit in a circular polar orbit around Earth, passing directly over the North and South Poles.
Step-by-step explanation:
Polar-orbiting satellites are useful for looking at a time series loop of images for one particular location. These satellites are in a circular polar orbit around Earth, meaning that they pass directly overhead at the North and South Poles. By orbiting in this way, they can capture images of the same location at different times, allowing scientists and researchers to create a time series loop of images for that specific area.
