Arizona Island located in the southwest of the United States approximately covers an area of 11,400 square miles.

Probably owing to the fact that Rhode owns less land, whose population is less than 1 million. In contrast, Arizona exactly has four times population that is 4 million. Natural environment in Arizona is obviously dry. One reason for this could be that it is a totally landlocked area without seashore characterized by extremely low rainfall, undoubtedly cause a large number of desert area. Whereas, Rhode Island lies on the Atlantic Ocean fortunately having long coastline, as a consequence of which, the city is a typical temperate zone with quite abundant rainwater, basically can reach an average of 44 inches of rain per year.
