What is weather Earth is surrounded by a layer of air called the atmosphere The way the atmosphere behaves is always changing It is these changes that give us the weather which may be hot cold wet windy or sunny Earth Sun The atmosphere is filled with moving air and clouds Mind the wind doesn’t blow your hat off Why does weather happen The sun is the nearest star to Earth It is far far away in space but its incredible heat warms our planet This warmth affects the way that air presses against Earth’s surface Differences between cold and warm places create strong winds as well as currents in the oceans 4 South Pole
Why do seasons change As Earth travels around the sun it is tilted This means that northern and southern parts lean toward to the sun at different times of the year So when the north part is leaning towards the sun it is summer there and winter in the southern part Tilted Earth North Pole Summer in the north Sun Winter in the south We call the weather conditions recorded over many years the CLIMATE is weather important Yes it is because people animals and plants need sunshine warmth and water to stay alive However extreme weather conditions such as storms or floods can put lives in danger Equator Rain and sunshine help us make food Then insects help new plants to spread 00
What makes water wonderful Water is a liquid It can freeze to become solid ice It can turn into a gas called water vapor Water may change its form but it lasts forever 2 It gets gassy Heat from the sun turns water into a gas led water vapor cal This is evaporation Water is precious Fresh water keeps us alive Water helps plants grow too We can wash in it swim in it sail on it and play in it Whoosh Splash 1 There’s lots of it Over two thirds of Earth’s surface is covered in water 6
3 it rises and cools 4 As warm water vapor rises it cools It condenses turning back into liquid It makes clouds Water droplets or solid ice crystals gather around specks of dust and form clouds 5 İt falls back down Don't forget your umbrella The higher you go the colder it gets Water droplets or ice crystals form raindrops or snowflakes which fall back to Earth 6 it goes on and on Rain and melted snow fill rivers lakes and oceans then the whole water cycle starts all over again It helps create our weather 7
