Contour lines that are relatively close together indicate a slope that is fairly steep. Contour lines that are further apart indicate a slope that is relatively flat. The area of the map above boxed in orange shows an area that has a fairly steep slope, while the area boxed in purple is a relatively flat area.

When contour lines are broadly spaced it means we don't require much information about that area as the area is flat
on the other side if contour lines are more in number closely spaced it means every single detail of that area is needed for consideration of project
.
hence more no of contour lines means more info about the topography of that area.

**Explanation:**
Contour lines on a map are used to represent the shape, elevation, and slope of the land. They are lines that connect points of equal elevation. The spacing between contour lines can provide information about the steepness of the terrain.
**Broadly spaced contour lines** indicate a relatively flat area. This means that the elevation change over a given distance is minimal. The contour lines are spread further apart, indicating a gentle slope or a generally flat surface. In other words, the change in elevation from one contour line to the next is small.
When contour lines are closely spaced, it indicates a steeply-sloped area or a change in elevation over a short distance. Closer contour lines mean a steeper slope, while widely spaced contour lines suggest a flatter or more gently sloping terrain.
**Why is option 'A' correct?**
Option 'A' states that broadly spaced contour lines indicate a flat area. This is the correct answer because when contour lines are widely spaced, it suggests a flat or gently sloping landscape with minimal changes in elevation over a given distance.
If the area was steeply-sloped (option 'B'), the contour lines would be closely spaced to indicate the rapid change in elevation. Similarly, if the area was a vertical cliff (option 'C') or an overhang cliff (option 'D'), the contour lines would be tightly packed together, showing a sudden and drastic change in elevation.
Therefore, the correct answer is option 'A' - broadly spaced contour lines indicate a flat area on a map.
