GEOGRAPHY IGCSE: GEOGRAPHICAL SKILLS - CONTOURS AND SPOT HEIGHTS
Download as PPTX, PDF0 likes1,338 views
The document explains geographical skills related to contour lines and spot heights on maps. Spot heights indicate specific points' elevations, while contour lines represent areas of equal height, illustrating steep or gentle slopes. These tools are utilized to create cross-sectional diagrams to visualize real-life landscape features.

- 2. On a map, height is shown in metres above sea level. Spot heights show the height of a particular point on the map.
- 3. Contour lines are added to a map to show height and gradient. On OS maps they are shown as thin orange or brown lines, some of which have the land height written on them. The lines join areas of equal height: • Contour lines that are close together show land that increases or decreases in height quickly. This is steep land. • Contour lines that are far apart show land that increases or decreases in height slowly. This land is gently sloping.
- 4. We can use contour lines to create cross-section diagrams of landscapes. This helps to match contour lines on the map to landscape features in real life, eg hills, valleys and spurs of land.
