10. If contour lines cross or intersect on a topographic map thismost likely represents __

## Step 1<br />Contour lines on a topographic map represent lines of equal elevation. This means that each contour line represents a specific elevation above or below sea level.<br /><br />## Step 2<br />When contour lines cross or intersect, it indicates that the map is incorrect. This is because the same elevation cannot exist at two different points at the same time.<br /><br />## Step 3<br />However, in some cases, contour lines may appear to cross or intersect due to the map's scale or the contour interval used. This is not a mistake, but rather a result of the map's scale and the contour interval.<br /><br />## Step 4<br />When contour lines cross or intersect, it most likely represents an error in the map's creation. This is because the same elevation cannot exist at two different points at the same time.
