Which colour is used to represent contour lines on a map?Group of answer choicesbrownredgreenorange

Contour lines on a map are typically represented using the color brown. This color is chosen because it effectively contrasts with many other elements on the map, making the elevation changes clearly visible.

Contour lines indicate points of equal elevation above a reference level, which is usually sea level. By using brown, cartographers ensure that the lines are distinguishable from water features, which are often depicted in blue, and vegetation, which might be represented in green.

Brown lines on a topographic map provide vital information about the terrain's shape and slope, allowing users to interpret the landscape more effectively. The intervals between the contour lines also give insight into the steepness of the land; closer lines indicate steeper slopes, while wider intervals suggest gentler slopes.

In summary, the choice of brown for contour lines is not only a standard practice in cartography, but it also enhances the readability and functionality of the map for users.
