Why is road construction easier in plains?

Answer and explanation

Correct answer: The land is flat

The governing concept is the relationship between relief and transport infrastructure. Plains generally have gentle slopes and fewer abrupt changes in elevation than mountainous or deeply dissected areas. As a result, engineers usually need less cutting, tunnelling, bridging, and sharp grade correction when laying a road, so construction and vehicle movement are comparatively easier and less costly. Therefore, option A is correct: the relatively flat land is the direct physical reason. Option B is false because plains do not always have snow. Option C is false because many plains contain rivers, groundwater, wetlands, and irrigated areas. Option D is also false; plains often support dense populations, which may actually increase the need for roads. Local soil, drainage, flooding, and land acquisition can still create challenges.
