Areas along coastlines, such as Florida, often do not experience winters as severe as areas inland, even though some of these coastal areas lie further north. Why do coastal areas tend to have milder winter weather patterns?
Cold ocean currents only flow east to west and cannot reach inland areas.
Warm ocean currents only flow east to west and cannot reach inland areas.
Cold ocean waters cool the air above them, the cool air flows over coastal areas, but cannot reach the areas inland.
Warm ocean waters heat the air above them, the warm air flows over coastal areas, but cannot reach areas inland.

Solar energy does not warm Earth’s surface evenly. For example, during the day, land areas warm up faster than nearby bodies of water. How does this uneven warming affect the movement of air over land and water?
The cooler, denser air above the water flows toward the warmer, less dense air above the land, causing a sea breeze.
The warmer, less dense air above the water flows toward the cooler, denser air above the land, causing a land breeze.
The cooler air over the water would absorb water vapor and rise, resulting in rainy conditions over the shoreline.
The warmer air over the land would transfer energy to the cooler air by conduction, leading to a uniform air temperature.
During a summer day on the beach, the sand and the air temperature feel warmer than the ocean water. At night, why would the ocean water be warmer than the air?
As a cool breeze blows off the water onto the land, the water warms up.
The heat from the air transfers to the water during the night, making the water warmer.
Air changes temperature faster than water, so the water is warmer and the air is much cooler than it was during the day.
Air stays warmer longer than water, so your body is warm when you jump into the water.
