Compasses
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 . . . .
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

NE
ESE
Compass bearings
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
Step 1 and 2 X A
Step 3 & 4 The bearing of A from X is 135 X 135 A
180 X The bearing of B from X is 180 + 67 = 247 B 67
How can we work out distances on a map? Distance and Scale How can we work out distances on a map?
How do we measure distances on a map?
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)
SCALE 4 cm
Distance 1:50000 50000cm 500m 500m 0.5km 4cm 4 x 0.5 = 2km
SCALE 1 2 3 4 5 1000m 2km

Interpreting the physical environment shown on a map
How can we measure relief on a map? Finding Heights How can we measure relief on a map?
Types of physical features Hill and mountain Valley Plateau Ridge
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.
Contours All the points on this contour are 100m above the sea level 80 60 40 The land between these contour is above 80m but less than 100m above sea level
Contours are far apart land is gentle 100 80 60 40 Contours are far apart land is gentle
Contours are close together land is steep 100 80 60 40 Contours are close together land is steep
100 80 60 40 Gentle steep
Hill and Mountain Hill less than 600m Mountain above 600m
Valley Low area between hills or mountains Most valleys contains streams and rivers
Plateau Upland area Steep slopes Broad, flat top
Ridge Upland area Long, narrow and steep-sided
Interpreting the Human Environment Settlements Transport lines Land use
