Step-by-step solution
1. Topographic surveys map the physical and geographical features of the Earth's surface. 2. They are carried out to show natural features such as rivers, hills, lakes, and forests. 3. Cadastral surveys deal with property boundaries, while engineering surveys collect data for construction design. Answer: C
Explanation
Topographic surveys are specifically conducted to determine and map the natural and physical features of a region, such as rivers, lakes, hills, and contours. Cadastral surveys focus primarily on legal property boundaries, whereas engineering surveys prepare data for construction works. Therefore, mapping natural landscape features falls under topographic surveying.
Why the other options are wrong
A) Cadastral surveys are used to determine legal property boundaries and ownership limits. B) Engineering surveys are conducted to collect design data for construction projects. D) Option C is correct as topographic surveys show natural features.
Shortcut
Topographic survey = mapping Topography (natural features like rivers and hills).
Common mistake
Confusing topographic surveys that show natural features with cadastral surveys that define legal property boundaries.
Correct answer: C) Topographic survey
