Answer and Explanation:
The factor that does not belong in the list of factors affecting the shape of Florida is mining.
Coastal erosion, saltwater intrusion, and sand dunes are natural processes that directly impact the shape of Florida's coastline. Coastal erosion refers to the gradual wearing away of land by waves, tides, and currents, which can reshape coastlines over time. Saltwater intrusion occurs when saltwater infiltrates freshwater aquifers, affecting the availability of freshwater resources in coastal areas. Sand dunes are natural formations that can be found along Florida's coastlines and contribute to the overall shape of the state.
On the other hand, mining is a human activity that involves extracting minerals or other valuable resources from the Earth. While mining can have environmental impacts, such as changing the landscape and causing habitat disruption, it does not directly influence the shape of Florida as the other factors listed do.
Therefore, mining does not belong in the list of factors that affect the shape of Florida.
