Topography refers to the arrangement of the natural and artificial physical features of an area. It includes elements such as mountains, valleys, rivers, and plains, which together create the landscape we see. Understanding topography is essential for various fields, including geography, urban planning, and environmental science, as it influences climate, vegetation, and human activities. The study of topography also involves mapping these features, often using tools like contour lines and GIS (Geographic Information Systems). This information is crucial for activities such as construction, agriculture, and conservation, helping to ensure that land is used sustainably and effectively.
