1. Contours NEXT  Click the NEXT  only when you are ready to move onto the next slide These slides will slowly tell you about contours wait until you see the NEXT  button to move on.

6. Let’s look at some other examples NEXT 

7. Think where is the steepest slope on this island? Click here to see if you’re right xxx XXXX XXXX 50 100 150 200

8. Sometimes spot heights can be shown as a dot with a note of the height of that particular place. A trigonometrical point (or trig point) shows the highest point in an area (in meters) and is shown as a blue triangle Steepest slope – contour lines are closest together Sparrow point 227 . 76 xxx XXXX XXXX NEXT  50 100 150 200

9. You can spot other features by the shape and pattern of the contours NEXT 

10. A valley may look like this… Often with a river running down through the valley 150 120 90 NEXT 

11. However a spur can look very similar ! But here the heights are increasing in the opposite direction – always double check which way the contours are increasing or decreasing. 90 120 150 NEXT 
