The land breeze phenomenon is characterized by cool air moving from the land to the sea at night. This occurs due to differential cooling rates between land and water. During the day, land heats up more quickly than water, causing warm air to rise over the land and creating a sea breeze as cooler air moves in from the ocean. At night, however, the land cools rapidly while the water retains heat longer. As a result, the cooler, denser air over the land flows toward the relatively warmer water, creating the land breeze effect. This is an important dynamic in meteorology, as it influences local weather patterns and can affect coastal environments.

In contrast, the other options describe processes that do not accurately reflect the temperature and pressure dynamics involved in a land breeze. For example, a breeze moving from the sea to the land at night would be classified as a sea breeze, not a land breeze. Similarly, warm air rising from the sea represents an opposite phenomenon to what occurs during a land breeze. Wind patterns varying by temperature differences describe broader atmospheric behavior but are not specific to the land breeze phenomenon.
