Contour maps with closed lines that increase in value towards the center represent: (MCAER 2017)

✔Explanation: In topographic maps, closed contour lines with increasing values towards the center signify a hill or mountain. The increasing values represent higher elevations, with the center of the closed contours marking the peak or summit.
🔑KEY POINTS:
Contour:
Line joining points of the same elevation are called contour lines.
Contour Interval:
-The elevation difference between two consecutive contours is called contour interval.
-It is always kept the same for a map.
Horizontal equivalent:
The horizontal distance between two consecutive contours is called equivalent.
Hill → Closed contour lines with higher values inside indicate a hill Depression – Closed contour lines with lower values inside indicate pond or depression.

Overhanging cliff → Two contours of different elevations cannot cross each other except in the case of a vertical cliff.
Vertical cliff → Contour lines of different elevations unite to form one line.

Ridgeline/valley line intersect contour at a right angle. (Line joining topmost point of a hill is called Ridgeline and the line joining bottom-most points of a valley is called Valley line.)
