Methods of representing Relief - SS2 Geography Past Questions and Answers - page 2
How do hachures differ from contour lines?
Hachures represent elevation values directly.
Contour lines indicate the direction of water flow.
Hachures show the steepness and slope direction.
Contour lines are used for political boundary marking.
What do relief coloring and hill shading both help with on a map?
Identifying city centers
Depicting population density
Enhancing the representation of terrain
Showing transportation networks
What information do spot heights typically provide on a map?
Precise longitude and latitude
Temperature variations
Elevation above sea level
Distance to the nearest city
Boundary pillars are useful for demarcating:
Natural features like rivers
Political boundaries
International time zones
Climatic zones
Trigonometrical stations are primarily used for:
Identifying flora and fauna
Measuring astronomical data
Calculating distances and angles in surveying
Providing information about cultural landmarks
Explain how contour lines are used to represent the topography of an area.
Contour lines are used to show the elevation and shape of the terrain. They connect points of the same height, helping us understand the landscape's highs and lows.
Why is it important to have benchmarks on a map, and how are they established?
Benchmarks are essential as they provide known elevation points for surveying and mapping. They are typically established by surveyors using precise instruments.
Describe the differences between relief coloring and hill shading in map design.
Relief coloring uses colors to represent elevations, while hill shading adds shadows to depict the terrain's 3D nature.
How can hachures be useful for hikers and outdoor enthusiasts when reading a topographic map?
Hachures help hikers by showing the steepness and direction of slopes, aiding in route planning and terrain understanding.
Discuss the significance of trigonometrical stations in accurate surveying and mapping.
Trigonometrical stations are crucial for accurate surveying and mapping as they provide elevated points for measuring distances and angles, which are fundamental in creating precise maps.
