Question 7

Why does a sea breeze blow from the sea to the shore during the day but reverse itself at night?

Answer 7

As the land warms during the day, the air above it also warms, causing rising convection currents above the land. The cool air above the ocean flows in to replace the rising warm air. At night the land cools below the temperature of the sea. The warmer air above the sea rises (convection current), and the cooler air from the land flows in to replace it. This revers is caused by temperature fluctuations on land but very little temperature fluctuation in sea water.
