Question

State the three methods used to show the earth's relief features on a map.

Answer 1

To showcase the earth's relief features. The primary methods employed include hachures, hill shading, form-lines, and contours.

1. Hachures: are short, unconnected lines that follow the slope. They depict the direction of free-flowing water down a hill.
2. Hill Shading: The hill shading method uses the 'light and shadow effect' to depict relief in a region. This method assumes that when a source of light, such as a large lamp, is used to illuminate the relief model, shadows of landforms appear.
3. Form-lines: Form-lines are broken contour lines that connect sites with the same height above sea level. These images simply show the overall pattern of the ground and do not provide specific height information. This strategy is used when precise data is unavailable for complex relief areas.
