The experiment conducted using glass filled with water and card board indicates that air exerts pressure.

Carbon monoxide is an air pollutant whereas carbon dioxide is considered as a greenhouse gas.

A ball falling down to the ground is due to gravity and not due to air pressure. Hence, it doesn't show that air exerts pressure.

When winds blow over a week roof, it creates a low pressure over it and a high pressure inside causing the roof to be blown off. Opening the doors and windows reduces this pressure difference and avoids the roof from being blown off.

Because of the curved upper surface of the aeroplane more air flows in the same time as compared to the lower surface. Therefore, the pressure over the aeroplane is less when compared to the lower surface.

As we know air is a bad conductor (It consists of mostly nitrogen and oxygen which are electrically neutral and are not easily ionized) of electricity. So, Overhead cables need not be insulated.

Sea breeze is a breeze blowing towards the land from the sea, especially during the day owing to the relative warmth of the land

On freezing water drops they converted in ice.

The humidity of a place varies from time to time as it also depends on the place we reside in. Coastal areas have more humidity or is more humid due to the pressure of the sea breeze.

Convection plays a major role in the formation of a thunderstorm. When warm air rises and meets the cold air, it condenses (releases latent heat). The heat helps fuel the thunderstorm. Then the downdraft forms, bringing cold air and precipitation down to the earth's surface.
