Boundaries or Borders
Boundaries refer to physical or imaginary lines that separate one area from another, such as between countries or regions. Borders are the actual physical lines or areas that mark the limits of these boundaries. Borders can be defined by natural features like rivers or mountains, or they can be man-made structures like walls or fences.
New York's boundaries are Vermont, Massachusetts, New Jersey, Philadelphia, and Connecticut.
The three kinds of borders are physical borders (e.g. walls, fences), political borders (e.g. boundaries between countries or states), and cultural borders (e.g. language, customs).
Territorial boundaries are lines that separate countries or regions, while modern state borders are the formal boundaries that delineate the sovereignty of a state. In many cases, territorial boundaries serve as the basis for establishing state borders, but political agreements, treaties, and historical events can also influence the final demarcation of state borders. Ultimately, modern state borders are a product of diplomatic negotiations and international agreements that may or may not align precisely with older territorial boundaries.
