Year 7 Exam Review Make sure you know the Middle East Countries and the Continents and Oceans! Use the map in your textbook on page 140-141 to find the answers. Compass Directions YOU NEED TO KNOW ALL 8 POINTS OF THE COMPASS ROSE SO YOU CAN QUOTE DIRECTIONS WHEN YOU USE A MAP Use these examples to help you: Bamford is NORTH-EAST Thornhill Shatton is SOUTH of Thornhill Offerton Moor is SOUTH-EAST of Westfield Brough is NORTH of Elmore Hill Farm Aston is WEST of Bamford Bamford is EAST of Aston Thornhill is SOUTH-WEST of Bamford Practice questions in your textbook on page 28 # 1-4. Scale The scale of a map allows a reader to calculate the size, height and dimensions of the features shown on the map, as well as distances between different points. The scale on a map is the ratio between real life sizes and how many times it has been shrunk to fit it on the map. The scale below is for a 1:50,000 scale map. At this scale, 1 cm on the map represents 50,000 cm on the ground (= 500 metres or 0.5 kilometres). Practice questions in your textbook on page 27 #1, 2, 4. Symbols and Map Keys Symbols are used on a map instead of drawing the exact thing to save space – imagine trying to draw all the houses and trees on! Practice questions in your textbook on page 3 #1, 2. Don’t worry you do not need to learn them all! You will always be given a key to use in an exam! Latitude and Longitude Latitude Measured in degrees NORTH and SOUTH of the Equator. Lines are parallel to each other running from WEST to EAST. Longitude Measured in degrees EAST or WEST of the Prime Meridian. Lines drawn running NORTH and SOUTH. 4 Figure Grid References Most maps are divided into small squares by grid lines that run horizontally (eastings lines) and vertically (northings lines) across the map. Each line has a number (or sometimes a letter) so we can give a reference for each square to help us locate where somehting is on a map. To give a grid reference for a whole grid square we use 4 figure grid references to locate it on the map. This is how you give a 4 figure grid reference of a square on a map: 1. First you locate the bottom left hand corner of the square you want as it is from here that you take your reading. 2. Then you go along the corridor until you get to the correct eastings line (those which run side to side) for your square (31) 3. Then you up the stairs until you find the correct northings line (which run top to bottom) for your square (25) 4. So the 4 figure grid reference for the green square is 3125 SOME EXAMPLES OF 4 FIGURE GRID REFERENCES TO HELP YOU: BAMFORD is in grid square 2183 THORNHILL is in grid square 1983 BROUGH is in grid square 1882 ASTON is in grid square 1883 BAMFORD STATION is in grid square 2082 Practice questions in your textbook on page 25 #1, 5, 7, 8.
