Three of the statements are correct. 1. Ireland produces more CO2 than Netherlands. 2. Ireland produces more CO2 per person than Belgium. 3. The USA produces much more CO2 than all of South America and Africa. 4. Germany produces more CO2 per person than Canada. 5. North America produces more CO2 than Western Europe.

According to the map, which of the following statements are correct? A. Ballsbridge, Ringsend and Sutton would all be part of the sea. B. Coolock, Clonskeagh and Dundrum would all survive the rising sea levels. C. The north Dublin suburbs of Beaumount, Ranelagh and Donnycarney would all still be part of the land. D. Dublin Bay would become smaller. E. Howth would be a new island. The correct statements are: Tick (3) the correct box. A, C, E A, B, E 3 B, C, D A, C, D 35 New Complete Geography Skills Book 5 Examine Figure 5 and answer the questions that follow. 90º lines of latitude winds 60° N Low Pressure B Polar Winds Atlantic Ocean 30° N High Pressure South Westerly (Anti-Trade) Winds C 0° Low Pressure A North-Easterly Trade Winds 0º 5 (a) Circle the correct response to each of the statements (i) to (v) below: (i) The line of latitude at A is called the: Tropic of Cancer / Equator / Tropic of Capricorn. (ii) When travelling from A to B on the earth, the climate would: change from warmer to colder / change from colder to warmer / not change at all. (iii) The winds that blow over Ireland are called the: trade winds / anti-trade winds. (iv) The area at A is known as the: doldrums / horse latitudes. (v) The winds at C tend to warm / cool the areas over which they blow. (b) Complete Figure 4 by filling in the boxes in the diagram. (i) The lines of latitude (in the boxes on the left side). (ii) High pressure or low pressure (in the boxes in the centre). (iii) The names of winds (in the boxes on the right). 36 Chapter 8 6 Ocean currents (a) Examine the map in Figure 6. Circle the correct answer in each of the statements below. (i) The current at X is a warm / cold current. X (ii) The current at Y is a warm / cold current. Y (b) Name the current that is labelled X. _________________________North Atlantic Drift (c) Name the current that is labelled Y. 6 _________________________Canaries Current (d) The ocean current labelled X has several effects on Ireland. Describe two of those effects. l _____________________________________________________________________________[See page 81 of textbook] _____________________________________________________________________________ _____________________________________________________________________________ _____________________________________________________________________________ _____________________________________________________________________________ _____________________________________________________________________________ _____________________________________________________________________________ l _____________________________________________________________________________ _____________________________________________________________________________ _____________________________________________________________________________ _____________________________________________________________________________ _____________________________________________________________________________ _____________________________________________________________________________ _____________________________________________________________________________ 37.
