Topo lines form concentric circles around hills and mountains. The lines are closer together on steeper slopes, and farther apart on gentler slopes. The lines never cross, and uphill is always perpendicular to the lines.
Topography can influence local climate, weather patterns, and water flow in a region. Mountains and valleys can create barriers that impact precipitation and temperature, leading to different microclimates within the same area. Additionally, topography can affect land use, agriculture, and settlement patterns by providing constraints or opportunities for development.
Cliff ­- Marked by a sudden drop in height on a contour map Spur - A protrusion from a cliff. It is shown by an area of high land continuing out from a cliff while its surrounds are nearer ground level. Ridge - Shown by continuous elevation for some distance. Saddle ­- Appearing a lot like a saddle from a side view, it is the area between two hills. Valley ­- A depression in the ground, similar to a hill, but instead the area surrounding the valley is higher.
