Final answer:
Florida is more humid than Arizona due to the evaporation of water in humid climates helping to limit high temperatures.
Step-by-step explanation:
The state of Florida is more humid than that of Arizona. In very humid climates, such as Florida, where there are numerous bodies of water, the evaporation of water helps limit high temperatures. When water evaporates, it absorbs heat energy from the surroundings, including the air. This process cools down the air, preventing temperatures from rising too high.
