Which of the following statements about geographic boundaries is false? A. Geometric boundaries can lead to conflict when they cross or ignore obvious physical boundaries. B. Natural physical forms can create boundaries between states. C. Physical boundaries follow straight, geometric boundary lines. D. Lines of longitude and latitude are used to calculate straight boundary lines. Please select the best answer from the choices provided. A B D

The correct answer is C. Physical boundaries follow straight, geometric boundary lines.<br /><br />Explanation:<br />A. Geometric boundaries can lead to conflict when they cross or ignore obvious physical boundaries. This statement is true. Geometric boundaries are artificial boundaries that are drawn based on straight lines or arcs, often without regard to natural features or cultural divisions. These boundaries can lead to conflicts as they may cut through communities, ethnic groups, or economic zones.<br /><br />B. Natural physical forms can create boundaries between states. This statement is true. Natural physical forms, such as rivers, mountain ranges, or coastlines, can serve as natural boundaries between states or political units. These natural boundaries are often easier to define and accept as they are based on physical features rather than human-made lines.<br /><br />C. Physical boundaries follow straight, geometric boundary lines. This statement is false. Physical boundaries are based on natural features, such as rivers, mountains, or coastlines, and do not necessarily follow straight, geometric lines. They can be irregular and follow the natural contours of the landscape.<br /><br />D. Lines of longitude and latitude are used to calculate straight boundary lines. This statement is true. Lines of longitude and latitude, also known as geographic coordinates, can be used to define straight boundary lines, especially in the case of geometric boundaries. These lines are imaginary lines that run parallel to each other and can be used to establish straight boundary lines on a map or in a geographic information system (GIS).
