The contour interval on a map represents the difference in elevation between two adjacent contour lines. Contour lines are used to represent the shape and relief of the land on a map. They connect points of equal elevation above a reference datum, such as mean sea level.
The contour interval is the vertical distance between contour lines and is usually indicated in the map legend. A contour interval of 50 meters means that each contour line on the map represents an elevation that is 50 meters higher or lower than the adjacent line. Similarly, a contour interval of 100 meters means that each contour line represents an elevation that is 100 meters higher or lower than the adjacent line, and so on.
Therefore, the correct answer to the question depends on the specific map being referred to. It could be any of the options given, or a different value altogether.
