what is the difference between natural and artificial boundaries?

Answer 1

A natural boundary (between countries, regions, continents) would be a naturally occurring feature like a river (the Rio Grande between the US and Mexico) or mountain range ( the Urals between Europe and Asia).

Answer 2

A natural boundary is a physical feature such as a river, ocean, or mountain range. It is where a piece of land stops (river) or abruptly changes direction (mountain peak). From far enough away, you can "see" a natural boundary. An artificial boundary is a political feature that is defined by treaty, war, or law; you cannot see it (unless it has been artificially marked, like a fence or tree break between countries). Artificial boundaries tend to be straight lines or arcs, and often tend to be along lines of latitude or longitude; they can also be rough midpoints between two (or more) conflicting claims, such as the Maine/New Brunswick border or the North Korea/South Korea border. They can also be equidistant or proportional-share slices of a body of water, such as how Russia, Iran, Turkmenistan, Kazakhstan, and Azerbaijan "split up" the Caspian Sea or how the US and Canada divvy up the Great Lakes. As a piece of trivia, the only state in the USA that does not have at least one "straight line" boundary is Hawai'i, because it does not border any other state.

Answer 3

natural boundaries are things like rivers or mountain ranges whereas an artificial boundary is a line drawn in the sand.

Answer 4

Boringbro is right, but he forgot to add that artificial boundaries (like borders which are straight lines) are man-made, such as an arbitrary line, a wall, or a fence.
