A geographical line is an imaginary line that helps define boundaries or features on the Earth's surface. These lines can represent political borders, such as the Equator or the Prime Meridian, or natural features like rivers and mountain ranges. They are essential for mapping and navigation, providing a way to understand the layout of different regions. Geographical lines are often used in various fields, including geography, cartography, and environmental science. They help in studying climate zones, ecosystems, and human activities. By understanding these lines, we can better appreciate the relationships between different places and their characteristics.
