2 © Boardworks Ltd of 40 Why do geographers study the weather? What is the difference between 'weather' and 'climate? European climate – a decision-making exercise Climate graphs What is the water cycle? What is precipitation? Why does it rain? Learning objectives

3 © Boardworks Ltd of 40 The weather has an impact on many of the things that we do! Can you explain how the weather affects these people? Why do geographers study the weather?

6 © Boardworks Ltd of 40 Climate is the overall pattern of weather, usually based on an average over 30 years. Click on the buttons to find out about these types of climate. What is the difference between weather and climate?

7 © Boardworks Ltd of 40 The types of climate can be classified into 6 major zones. World climate zones

8 © Boardworks Ltd of 40 What climate zone do you live in? What other climate zones have you visited? World climate zones

9 © Boardworks Ltd of 40 Imagine that you are a tour operator. Decide which of these pieces of advice you would give to people depending on which climate zone they are planning to visit! World climate zones

11 © Boardworks Ltd of 40 Climate graphs are a way of showing how temperature and precipitation vary throughout the year for a particular place. Climate graphs

12 © Boardworks Ltd of 40 How to construct a climate graph…

13 © Boardworks Ltd of 40 2.Work out the right scale for each axis (look at your highest temperature and rainfall figures). 1.Draw and label the axes (remember you need two names for the y axis – temperature and rainfall ). 3.Draw the graph using bars for rainfall and a line for temperature. Remember to plot the temperature points in the middle of the months on the x axis. How to construct a climate graph…

How does it compare to this climate graph of London? Using data from an atlas draw a climate graph for another place, in the UK or somewhere else in the world. Plot your own climate graph

17 © Boardworks Ltd of 40 Climate can make a big difference to peoples holidays. European climate

18 © Boardworks Ltd of 40 Anna, the travel agent at Travelstar is having to deal with a difficult customer. Mr Strattle is very keen to go away on a city break in Europe. However, Mr Strattle is very fussy about things, especially the weather. He does not want to travel to travel anywhere where it might be cold and he really dislikes rain when he is on holiday. European climate

19 © Boardworks Ltd of 40 the holiday must take place in October. he doesnt want to visit a city where there will be a high risk of rainfall. he wants to visit a city with a reasonable temperature–not too cold. Mr Strattle has narrowed his choices down to four different cities. Can you help Anna find a suitable destination for him? Mr Strattle has decided that: European climate

20 © Boardworks Ltd of 40 European climate

21 © Boardworks Ltd of 40 At first Anna looks at London. However there is quite a lot of rain in London during October. Next Anna looks at Oslo. However, Oslo has even more rain than London. Warsaw does not seem to have much rain in October, but the temperature might be too cold for Mr Strattle. Eventually Anna finds a city that has a warm average temperature in October and does not have too much rainfall. Did you reach the same answer? Madrid European climate

23 © Boardworks Ltd of 40 70% of the Earths surface is covered by water. Store% Oceans and seas97 Snow and ice (mainly in the Arctic and Antarctic)2 In the atmosphere or on the land as rivers and lakes1 Water is neither created nor destroyed. It is cycled round over and over again. This recycling of water is called the water cycle. Draw a graph to show where the Earths water is stored. The water cycle

24 © Boardworks Ltd of 40 The water cycle

25 © Boardworks Ltd of 40 The water cycle

26 © Boardworks Ltd of 40 The water cycle in more detail

27 © Boardworks Ltd of 40 The water cycle – definitions

29 © Boardworks Ltd of 40 Precipitation is water from the atmosphere. It can be in solid or liquid form. Name as many different types of precipitation as you can! What is precipitation?

31 © Boardworks Ltd of 40 There are three main types of rainfall – relief, convectional and frontal. In all three situations, rainfall occurs because air rises. Air contains water vapour and as the air rises it cools and condensation can occur. This means that the water vapour returns back into minute droplets of water and falls as rain! Why does it rain?

32 © Boardworks Ltd of 40 Convectional rain

33 © Boardworks Ltd of 40 Convectional rain

34 © Boardworks Ltd of 40 Relief rain

38 © Boardworks Ltd of 40 Weather and Climate Bingo!

39 © Boardworks Ltd of 40 Geographers study the weather because it has an impact on peoples daily lives and the activities that they do. Weather is the day to day changes in the atmosphere. Climate is the overall pattern of weather, usually based on an average over 30 years. The British Isles has a temperate climate. This means that it is not too hot, not too cold, not too dry and not too wet! Water is neither created nor destroyed. It is cycled round over and over again. This recycling of water is called the water cycle. Precipitation is water from the atmosphere. It can be in solid or liquid form. There are three main types of rainfall – relief, convectional and frontal. In all three situations, rainfall occurs because air is forced to rise. Key Ideas
