What's the difference between the sea and the land in human body?

The temperature difference between day and night on land is large, but that between day and night on ocean is small. During the day, the land heats up quickly and the temperature is higher than that of the ocean, so a low pressure area is formed and the ocean forms a high pressure area. At night, on the contrary, the land is a high-pressure area, and the ocean is a low-pressure area, and the airflow blows from the land to the ocean.
