Final answer:
The correct summary of the distribution of people in Florida is that they experience warmer winters and cooler summers, consistent with Type C climates which support high population densities. Florida is an attractive destination in the Sun Belt due to its climate. So the correct option is A.
Step-by-step explanation:
The correct statement that accurately summarizes the distribution of people in Florida is A. The majority of people in Florida experience warmer winters and cooler summers than other regions. This is consistent with the general climate pattern of Type C climates which are favorable to human habitation, with the largest human population densities found in these areas. Florida has a subtropical to tropical climate and is part of the Sun Belt, attracting permanent growth due to various factors including its warmer climate.
Although Florida is surrounded by water, the notion that the majority of people live by a freshwater source may not be precise. Some live near coastal areas, which are salty. As for the distribution of population, more people tend to live in the warmer southern part of Florida, especially for retirement and the mild winter climate, which contradicts choice C about the majority living in North Florida. Finally, with respect to seasonal variation described in option D, Florida's seasons are less pronounced compared with regions that have a more continental climate.
