WEATHER
Sunshine, rain, wind, snow, hail, and fog are all kinds of weather. The weather is the day-to-day change in the atmosphere. Movements of hot and cold air, and different amounts of moisture in the air, can make the weather hot and still or cold and stormy.
>Climate is the type of weather that is usual in a particular part of the world. Tropical places are usually hot and wet. The polar regions are usually cold and windy. About half the people in the world live in countries with temperate climates, which are neither very hot nor very cold.
Up in the clouds
Clouds are an important part of the weather, bringing rain, hail, snow, or fog. They are made up of millions of water droplets or ice crystals, so tiny that they can float in the air. Clouds usually from in moist air over the oceans.
>Winds blow clouds over the land, where the water they contain falls to the earth as rain.
>Sometimes the water in the clouds freezes to make tiny ice crystals that fall as snow or hail
Thunderstorm and Tornado
thunderstorms often happened when warm and moist air meets cold air. huge storm clouds gather. The raindrops inside them join and grow very big, then fall in a great downpour. there maybe flashes of lightning made by giant sparks of electricity. They zigzag between the storm clouds and the ground. Thunder is the shock wave made when air suddenly expands as lightning passes through it.
>Thunder and lightning happened together, but we see lightning first because light travels faster than sound.
>Tornadoes are the strongest storms of all. They swirl into a funnel shape that can spin up to 400 miles per hour.
