![]() No one is exactly sure why lightning occurs, but scientists believe water droplets and ice particles bang together in the cloud, helping to build up positive and negative electrical charges.The warm air rises, creates clouds and condenses into light rain or snow.When a warm air mass moves over a cold air mass, a warm front happens.The warm air is pushed up above the cold air mass, which causes the warm air to cool and condense, resulting in a mild temperature and rainstorm.When cold air pushes under a warm air mass, a cold front happens.The area where two or more air masses meet is called a front.Cold air masses are areas of cold air that move in the same direction.Hot air masses are areas of hot air that move in the same direction.The two main types of air mass are hot and cold.An air mass is a huge area of air that shares the same characteristics.The primary cause of different types of weather is how air masses interact with each other.The processes involved in the water cycle are evaporation, transpiration, condensation, precipitation, and runoff.It involves the ceaseless circulation of water in the atmosphere. This movement of water is called the water cycle or the hydrologic cycle.The sun is the engine that drives the motion of water in our atmosphere.These weather conditions cause winds to blow. The sun and the moisture in the air work together to form clouds which make rain and thunderstorms.All of our weather happens in the bottom layer of the atmosphere, called the troposphere, which is six to ten miles thick.There is a blanket of air that surrounds the earth that is about 15 miles thick.Weather is impacted by things we can’t see like wind, solar radiation, humidity, and air pressure.Thunder is a loud rumbling noise heard due to rapidly heated air expanding.A storm is sometimes accompanied by thunder and lightning. When there is a strong wind and heavy rain, the weather is stormy. Wind gusts form when air is pushed into smaller spaces of vacuum.However, when warm air mass rises to the sky and cold air rushes to fill the gap, expect to have a windy day.A rainy day occurs when the temperature drops and the water vapor in the cloud cools and forms raindrops.Clouds are often associated with rain but cloudy days do not equate to rainy days. ![]() It can be warm on a cloudy day when the clouds trap in heat near the surface.When the weather’s cloudy, the rays of the sun are blocked from reaching the Earth’s surface.In fact, they can be cool too, depending on the time of year. When there are no clouds in sight, the sun is able to shine through and keep the environment warm.Sunny days are usually pleasant as most people like doing activities outdoors when the sun is up and shining.There are five types of weather: sunny, cloudy, windy, rainy, and stormy.Seasons and climate largely affect the weather.Depending on sunshine, heat, cloudiness, wind, and rain, weather changes on a daily basis.Weather is the condition of the atmosphere at a given place and time.See the fact file below for more information on the weather or alternatively, you can download our 27-page Weather worksheet pack to utilise within the classroom or home environment. The sun’s energy and angle directly affect the air pressure and temperature in the sky which results in a change in weather. It includes wind, rain, lightning, hurricanes, hail, snow, and more. It is what happens in the sky you can tell the weather by looking at the sky. Weather is the condition of the atmosphere. Download the Weather Facts & Worksheets.
