Compare what might be a difference between contour lines on a mountain and contour lines in a broad, flat valley?

The elevation difference between two adjacent contour lines is called the contour interval (CI). Usually the contour interval is noted on the map legend. In most topographic maps every 5th contour line is drawn in bold print or wider than other contours. Such lines are called index contour lines. Hope this helps!

answer: we can define a cultural region as a section of a land with cultural elements like religion, language, cuisine or architecture. cultural regions are different because its land for example can vary in size of few square miles to millions. they can also form cultural boundaries.

moreover cultural regions can be organized due to less difference between the same ethnic group. we can say also that exist three types of cultural regions such as the formal, functional and vernacular ones. for istance the formal regions refers to sharing cultural traits of people like religion or languages.
