A group of students want to investigate erosion occurring naturally on a riverbank. The students decide to take pictures of the riverbank each day over a period of 12 months, then record what changes they see in the photos. What is the MOST significant limitation to this type of investigation?
you may not be able to see how much of the land is eroded and the change wouldnt be as drastic over the course of 12 months, you would definetly need it over a longer period of time
