Answer:
• A river, mountain range, or stretch of shoreline are examples of physical elements in the natural environment that serve as natural boundaries between different regions. The dispersion of plants, animals, human populations, and communication can all be impacted by natural boundaries that might act as roadblocks.
• Language, religion, conventions, and political systems are examples of human activities and civilizations that can create a border. Cultural boundaries can overlap with or pass over natural limits since they are supple and flexible. Historical occurrences, migration trends, and cultural interchange frequently influence cultural boundaries.
• A geometric boundary is a man-made boundary that is determined by lines, points, or planes and is established using mathematical or Cartesian coordinates. When defining the borders of political entities like states, provinces, or counties, geometric boundaries are frequently utilised in mapping, surveying, and land management. Geometric borders can be altered and redefined as needed, unlike natural and cultural limits.
In conclusion, natural boundaries are actual aspects of the physical world, cultural boundaries are products of human endeavours and cultures, and geometric limits are man-made and based on mathematical coordinates.
