The uneven heating of the air causes the flow of the wind. It takes place due to the greater intensity of sunlight at the equator as compared to that of poles. Due to greater intensity of sunlight at the equator the air gets heated up, the air molecules absorb the heat and the intermolecular forces between the air molecules become weak and its kinetic energy increases. The air molecules becomes lighter and rises up. This creates a low pressure zone on the equator while high pressure zone exist at the poles. So, the air moves from high pressure to the low pressure.

When air is heated, it becomes less dense and rises, creating a region of lower atmospheric pressure at the surface.

The air molecules are held by strong intermolecular forces. During, the daytime when the air above the land gets heated up, the air molecules absorbs the heat and the intermolecular forces between the air molecules become weak and its kinetic energy increases. The air molecules move apart and become less dense and they become lighter and rises up. This creates a low-pressure zone on land and thus cold air from the sea rushes to land and thus creates sea breeze. Thus, the correct answer is option D.

Due to greater intensity of sunlight at the equator the air gets heated up, the air molecules absorbs the heat and the inter molecular forces between the air molecules becomes weak and its kinetic energy increases. The air molecules becomes lighter and rises up. This creates a low pressure zone on the equator. The air is cold at the poles as the intensity of sunlight is less so the cold air settles down and creates a high pressure zone above the poles. The air moves from high pressure to low pressure zone which is from poles to the equator at high speed and this may lead to precipitation of water vapor as rain.

During the day, the land gets heated faster than the water. The air over the land becomes hotter and rises up. The cooler air from the sea rushes in towards the land to take its place. The warm air from the land moves towards the sea to complete the cycle. The air from the sea is called the sea breeze.

During, the daytime when the air above the land gets heated up, the air molecules absorbs the heat and the intermolecular forces between the air molecules become weak and its kinetic energy increases. The air molecules move apart and become less dense and they become lighter and rises up. This creates a low-pressure zone on land and high pressure on above the sea thus cold air from the sea rushes from sea to land and creates sea breeze.

The freezer in the refrigerator is generally mounted on the top for proper cooling. The freezer cools the air. The air after getting cooled settles down and helps in proper and even cooling. Thus, the correct answer is option A.
