What Causes Weather ?

Weather  is the physical condition of the atmosphere at a particularly time. It includes temperature, air pressure and water content.

Weather is produced when air moves from place to place. This morning air is known as wind. Winds are formed when the cooler air moves in to replace the rising warm air. Warm air usually less dense than cool air; therefore, it creates low air pressure.Cool air is more dense and creates high air pressure.

Usually we have fine weather when the air pressure is high and there are clouds, rain and snow when the air pressure drops.
