1. Unequal Heating:

* Land heats up faster than water: During the day, the sun's rays warm the land much more quickly than the ocean. This is because land has a lower specific heat capacity, meaning it takes less energy to raise its temperature.

* Air above land warms: The warm land heats the air above it, causing the air to expand and become less dense.

2. Air Pressure Difference:

* Lower pressure over land: The warm, less dense air rises, creating an area of low pressure over the land.

* Higher pressure over water: The cooler, denser air over the ocean remains closer to the surface, creating an area of high pressure.

3. Wind Flow:

* Air moves from high to low pressure: Because nature seeks balance, air naturally flows from areas of high pressure to areas of low pressure.

* Sea breeze forms: This creates a consistent flow of air from the cooler ocean towards the warmer land, which we call a sea breeze.

In Summary:

A sea breeze is a localized wind system that blows from the sea towards the land during the day due to the difference in air pressure created by the unequal heating of land and water.
