the contour interval on a topographic map is

Answer 1

The contour interval on a topographic map is the vertical distance or difference in elevation between contour lines. It indicates how much elevation changes from one contour line to the next. For example, if the contour interval is 10 meters, each contour line represents a change of 10 meters in elevation. A smaller contour interval indicates more detailed elevation changes, while a larger contour interval shows broader changes in elevation over a given area. The contour interval can vary depending on the scale of the map and the terrain it represents.
