EEJ MAIN Aptitude QUESTION #10956
Question 1
On an architectural site plan, the contour lines are closely spaced on one side of the site and widely spaced on another. This indicates:
  • The close-spaced side is at higher elevation
  • The close-spaced side has a steeper slope✔️
  • The wide-spaced side has a steeper slope
  • The site is level at the centre
Correct Answer Explanation

Contour lines connect points of equal elevation. The spacing tells us about slope:

  • Closely spaced contours = terrain changes elevation rapidly over a short horizontal distance = steep slope ✓
  • Widely spaced contours = terrain changes elevation gradually over a long distance = gentle slope

This is fundamental knowledge for site analysis, drainage design, and determining buildable areas in architectural practice.
