Task 2: Revision of definition of topographic map: What do topographic maps allow geographers to identify? Landscape, the gradient of a slope, the relief, and the aspect, the height above sea level using contour lines Task 3: Contour What do contour intervals represent? On a map, they represent areas of equal elevation, the steepness of the slopes What are the contour intervals of the map shown? 20ft Task 4: Local Relief Local Relief is the difference in elevation between the highest and lowest points in a region. What equation is used to find local relief? Highest point - lowest point What is the local relief between points Z and X on the board? Local relief = 80ft Task 5: Gradient What equation do we use to find the gradient? Vertical interval rise __________________ Horizontal distance Run Rise (120-40)= 80m Run (ruler) 2km= 2000m What is the gradient between R & S? 1:25 Unsimplified = 80/2000 Task 6: Aspect What is the aspect of the slopes at points A, B, C & D? A: southeast B: south C: northwest D: west Task 7: Source analysis 1. What is the contour interval of this map? 50 metres 2. What is the local relief between points B & H? 100ft 3. What is the gradient of A and B (vertical interval 450m, horizontal distance 1000m) 450/1000 = 45/100 4. What is the aspect of Mount Florence in AR8746? SE
