Q – Can we REMEMBER how convectional rain is formed. Discuss with your table! EXT – Why do you think the weather is different across the UK ? WALT: Understand the factors affect the weather in the UK? WILFS. L4 – Describe the factors that affect the weather. L5 – Explain why the weather is different across the UK. L6 – Compare the weather across the UK and explain the differences. British climate Britain has a mild climate. It is in the temperate climatic zone and the sea affects the weather. In general, this means that Britain gets cool, wet winters and warm, wet summers. The weather conditions are also very changeable. Year Sevens • You have 5 tasks to complete on the Worksheet. • Each Table contains information that will help you. • You have 5 minutes per a table… • Only move when Mr Watkins tell you too… Prevailing Winds Prevailing winds is the winds direction in an area. The temperature of the wind and the amount of rainfall partly depend on where the air has come from. Looking at where the air has come from helps to explain the weather. A large body of air with similar characteristics is called an air mass. TASK: Label your wind… Use the posh words if you can remember them. Complete the fill in the gaps exercise as well. Winds that affect the British Isles: Latitude UK Places that are further north receive less concentrated energy from the Sun. The equator lies directly underneath the Sun and so countries that fall on the equator receive the most amount of sun. This means that in the Northern Hemisphere, the Sun’s energy becomes less concentrated and therefore the temperatures become cooler as you travel north. Africa Edinburgh TASK: Answer the Question on your worksheet. Cornwall Altitude • Temperatures decrease with height. The air is less dense and cannot be heated so easily. • Locations at a higher altitude have colder temperatures. Temperature usually decreases by 1°C for every 100 metres in altitude TASK: Draw an image to remind you of altitude. Remember it only has to be small ! Distance from the Sea Coastal areas are most affected by the sea. The sea takes longer to heat up and cool down than land. So in the winter the sea keeps coastal areas warm and in summer, it cools them down. TASK: Colour the image to show areas that would be warmer and colder ! Extension – What's the difference between winter and summer at the coast? Ocean Currents The effect that ocean currents have on the temperature depends on whether the ocean current is hot or cold. Britain’s mild climate is partly due to the Gulf Stream, a large Atlantic Ocean current of warm water from the Gulf of Mexico. TASK: Create your own map of the Ocean Current – Extension – Why does Britain have a mild climate? TASK • You have a choice of tasks. Write a quick advert for a holiday brochure. Tell the customer about the weather in Cornwall (in the South East, during the Summer), it is nice and hot and there is not a lot of rain. Tell me about the Latitude! OR Explain why there is a difference of climate; - In the South of England to the North of England. - Why do mountainous areas of England experience colder weather? - Why does the coast have a breeze in the Summer? - What is an air mass ?
