Scale:

A ratio scale tells us what 1cm represents in centimetres eg
1:100,000 means 1cm represents 100,000 centimetres. When
converting from ratio scale to metres you take off the last 2
zeros
eg 1: 100,000 becomes 1000 metres. And vice versa when
converting from metres to ratio add 2 zeros eg 500 metres
becomes 1:50,000

Fill in the blanks below
Ratio scales        Sentence scale                  ___ kilometres
1: 200,000          1 centimetre represents 2000m     km
1: 100,000          1 _______________________       1 km
1: 75,000           1 _______________________       0.75 km
1: 50,000           1 centimetre represents 500m    ______
1: 25,000           _________________________       0.25 km
1: 10,000           _________________________       ______
1: 5000             _________________________       0.05 km
1: 1000             _________________________       ______

Maps drawn on progressively smaller scales increase the area of
the earth that can be shown, but reduce the amount of detail that
can be included. Maps drawn on progressively larger scales
decrease the area that can be shown but enable more detail to be
shown. This means, for example, that a map drawn to a scale of
1:20,000 covers a smaller area of the earth’s surface but shows
much more detail than a map drawn to a scale of 1:100,000.
Because the scale of a map shows the relationship between
distances on the map and distances on the ground it can be used
to calculate distances and areas.

“Where is it?” – Finding Grid References

An area reference (AR) is a 4 digit number which tells
us the general location of something on a map using the
northings (numbers increase towards north) and
eastings (numbers increase towards east)

                     Eg. AR 2346
                      easting           northing



A grid reference (GR) is a 6 digit number – a
coordinate which pinpoints the location of a feature on
a map.

To get the third digit required for each coordinate in a
GR we divide up each easting and northing into tenths.

                   Eg. AR 23_ 46_
                      easting           northing

Understanding Contour Lines

           A contour line is a line on a map that joins places that are the same height above sea
           level. Things you should know about contour lines are shown below.


                                             Because the surface of the earth
 A contour line usually has                  goes up and down, each contour
 numbers printed on it. These                line is usually a different height to
 tell us the height of the land              the one next to it
 along that line.

                                                                                         Contour lines

Geography Skills Revision

  • 2. Maps and Mapwork 1. Compass Directions 1. What are the four main cardinal directions? Your answer: One way to remember the order of the four main compass directions is to make up a rhyme e.g. “naughty elephants squirt water” 2. What rhyme would you use to help you remember these directions? Your answer: 3. What are the eight main compass directions? Your answer: 4. What are the sixteen compass directions? Your answer: 5. Look at the simple map below. What direction must Philip go to get to the following places in the table? What direction is it from: Your answer Philip to the factory Philip to School Philip to the Football Ground Philip to Sara’s House School to the football ground Sara’s house to the factory Football ground to the factory Page 2 of 30
  • 4. Scale: A ratio scale tells us what 1cm represents in centimetres eg 1:100,000 means 1cm represents 100,000 centimetres. When converting from ratio scale to metres you take off the last 2 zeros eg 1: 100,000 becomes 1000 metres. And vice versa when converting from metres to ratio add 2 zeros eg 500 metres becomes 1:50,000 Fill in the blanks below Ratio scales Sentence scale ___ kilometres 1: 200,000 1 centimetre represents 2000m km 1: 100,000 1 _______________________ 1 km 1: 75,000 1 _______________________ 0.75 km 1: 50,000 1 centimetre represents 500m ______ 1: 25,000 _________________________ 0.25 km 1: 10,000 _________________________ ______ 1: 5000 _________________________ 0.05 km 1: 1000 _________________________ ______ Maps drawn on progressively smaller scales increase the area of the earth that can be shown, but reduce the amount of detail that can be included. Maps drawn on progressively larger scales decrease the area that can be shown but enable more detail to be shown. This means, for example, that a map drawn to a scale of 1:20,000 covers a smaller area of the earth’s surface but shows much more detail than a map drawn to a scale of 1:100,000. Because the scale of a map shows the relationship between distances on the map and distances on the ground it can be used to calculate distances and areas. Page 4 of 30
  • 8. N Church shop school Post office Fish and chips Find the bearings listed below: 1. The bearing from the Post Office to the shop. 2. The bearing from the Fish and Chips to the Church. 3. The bearing from the school to the shop. 4. The bearing from the shop to the Post Office. 5. The bearing from the Church to the shop. 6. The bearing from the Fish and Chips to the Post Office. If you know that 1 cm on the map is the same as 1 km in real life. Find the distances listed below: 1. The distance from the Post Office to the Fish and Chips. 2. The distance from the School to the Post Office. 3. The distance from the Shop to the Church. 4. The distance from the Church to the Post Office. Page 8 of 29
  • 12. “Where is it?” – Finding Grid References An area reference (AR) is a 4 digit number which tells us the general location of something on a map using the northings (numbers increase towards north) and eastings (numbers increase towards east) Eg. AR 2346 easting northing A grid reference (GR) is a 6 digit number – a coordinate which pinpoints the location of a feature on a map. To get the third digit required for each coordinate in a GR we divide up each easting and northing into tenths. Eg. AR 23_ 46_ easting northing Page 12 of 29

  • 14. Understanding Contour Lines A contour line is a line on a map that joins places that are the same height above sea level. Things you should know about contour lines are shown below. Because the surface of the earth A contour line usually has goes up and down, each contour numbers printed on it. These line is usually a different height to tell us the height of the land the one next to it along that line. Contour lines always go up or down by the same amount each time. The difference in height between one line and the next is known as the contour interval Contour Interval 50m The places on different contour lines will be different heights The contour interval may be shown above sea level in words at the bottom of the map A place that is halfway between one contour line and the next will Follow a contour line around the map probably have a height to find out its height, or work out its that is about halfway height by looking at the heights printed between the heights on the lines above and below it. shown on the contour lines above and below it. Page 14 of 29
  • 24. (Students always like to correct a teacher: Find the mistakes below, correct them and rewrite on your own paper) Scale: There are a couple of ways to express scale. 1. Representative ratios 2. Sentence statement The rule of thumb for converting ratio scale into metres is to add 2 zeros The rule of thumb for converting metres into ratio scale is to take away 2 zeros. BOLTS: Stands for Boarder, Orientation, Length, Title and Source Bearings: Steps for finding a bearing 1. Put the midpoint over the place you are measuring from 2. Make sure that 180 degrees is facing south 3. Read it in an anticlockwise direction Area References: Are 6 figures references and given as northings before eastings Grid References: Are 4 figures references and given as northings before eastings Page 24 of 29
  • 25. THE BASICS – WEATHER MAPS Code Breaker Code Name What is it? Code Breaker Joins together areas Closer lines = strong 1016 Isobars of same air pressure wind and rough seas 1018 Far apart lines = calm weather and less wind Low Isobar numbers Cooler weather with Pressure decrease (get lower) rain, winds rotate System towards the centre clockwise and air rises L High Isobar number Fine weather, wind rotate Pressure increase (get higher) in anti-clockwise H System towards the centre direction and are gently descending Tropical Isobar numbers are Strong winds in a L Cyclone decreasing rapidly clockwise direction. Rain and are very close and strong winds together surround a calm centre Cold air overtakes Fall in temperature, rain. Cold Front warm air and forces The front moves in the the lighter warm air direction of the arrow to rise heads Warm air catches up Temperature rise, Warm Front with a pocket of cold sometimes light rain. Very air and is pushed up RARE in Southern Australia Rainfall in How much rainfall past 24 has fallen in the area n/a hours over the past 24 hours On a weather map wind direction is indicated by the direction of the arrow from the place in question. Wind speed is indicated by feathers on the end of an arrow (unless other values are given in legend) No wind or calm conditions is indicated by the following dot  Page 25 of 29
  • 26. Wind Reading wind direction from a map with arrows already marked.  Always label the wind from the direction that the wind is coming from  Ie.
