During a land breeze at night, the air over land cools and descends. This phenomenon occurs because land cools more rapidly than water after sunset. As the temperature of the land drops, the air above it also cools, becoming denser and heavier. This denser air then sinks, creating a high-pressure area over the land.

Meanwhile, the air over the warmer water maintains a relatively higher temperature, resulting in lower pressure. The cooler, denser air from the land moves towards the water, creating a breeze from land to water. This movement of cooled air helps to establish the characteristic airflow associated with a land breeze, indicating that the air over land is not only cooling but also descending due to its increased density.

The other choices do not accurately describe the behavior of air during a land breeze experience. Air cannot heat and rise as suggested in the option about heating and rising since it is the cooling of air over the land that prompts the descent. Stagnation of air does not occur because there is a clear movement of cooled air from land to water, and downward circulation is unnecessary to describe the land breeze, as it primarily involves horizontal movement towards the water.
