In which of the following two or more than two contour lines meet at a point ?

Question

Accepted Answer

A waterfall is the correct answer because contour lines represent lines of equal elevation. At a waterfall, the elevation changes drastically and almost vertically. This means that multiple contour lines, representing different elevations, will converge and essentially meet at a single point on a map. This convergence indicates a very steep or vertical drop, which is characteristic of a waterfall.

Here's why the other options are incorrect:

*   **Conical hill:** A conical hill is represented by a series of concentric, roughly circular contour lines. The contour lines get progressively smaller as they approach the peak, but they do not meet at a single point.

*   **Ridge:** A ridge is represented by elongated, roughly parallel contour lines that are close together. The contour lines indicate a high elevation area that slopes down on either side, but they do not converge to a single point.

*   **Gentle slope:** A gentle slope is represented by contour lines that are spaced far apart. This indicates a gradual change in elevation, and the contour lines do not meet at any point.
