The causes of weather

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

                Weather is produced when air moves from one place to another .this moving air is known as wind , winds are caused by warm air rising and cooler air moving in yo replace it. Warm air is usually less dense (lighter) than cool air.therefore,it creates low air pressure. Cool air is more dense (heavier) and creates high air pressure.
