4. Compasses

5. Compasses are used to show the direction of places on maps
Compasses are used to show the direction of places on maps. This is very important so that we can know how to use the map to move from one place to another.
There are 2 types of compass that you should use

6. The 4 point compass The 8 point compass North West East Never South
Wheat
Eat
The 8 point compass N NW NE
Shredded E W SE SW S

7. SW

8. NE

9. ESE

10. Compass bearings

11. Compass bearings
To show direction even more accurately, whole circle compass bearing may be used. Compass bearing are measured in degree.
Compass bearing are used to show the direction of one point from another more accurately

12. Step 1 and 2 X A

13. Step 3 & 4
The bearing of A from X is
135 X
135 A

14. 180 X
The bearing of B from X is
180 + 67 = 247 B
67

How can we work out distances on a map?

20. How do we measure distances on a map?

21. Measuring a straight line distance
This is very simple to use.
Use your ruler to rule the distance between the 2 places
Then compare your answer to the scale of the map (This is usually in the bottom corner of the map and for most maps that you use this will be 1cm = 50,000cm (0.5Km)

22. SCALE
4 cm

23. Distance
1:50000
50000cm 
500m
500m 
0.5km
4cm  4 x 0.5 = 2km

24. SCALE 1 2 3 4 5
1000m
2km

26. Interpreting the physical environment shown on a map

27. How can we measure relief on a map?
Finding Heights
How can we measure relief on a map?

28. Types of physical features
Hill and mountain
Valley
Plateau
Ridge

29. Contours
Imaginary lines that join places of the same height above sea level
They also represent the relief of a place
Tell us about the shape and slope of the land.

30. Contours All the points on this contour are 100m above the sea level80 60 40
The land between these contour is above 80m but less than 100m above sea level

31. Contours are far apart  land is gentle
100 80 60 40
Contours are far apart  land is gentle

32. Contours are close together  land is steep
100 80 60 40
Contours are close together  land is steep

33. 100 80 60 40
Gentle
steep

34. Hill and Mountain
Hill  less than 600m
Mountain  above 600m

35. Valley Low area between hills or mountains
Most valleys contains streams and rivers

36. Plateau
Upland area
Steep slopes
Broad, flat top

37. Ridge
Upland area
Long, narrow and steep-sided

42. Interpreting the Human Environment
Settlements
Transport lines
Land use
