If contour lines on a map are spaced closely together, it indicates a steep slope, possibly an uphill area. Conversely, if contour lines are spaced far apart, it suggests a gentle slope or a downhill area. By observing the pattern of contour lines and their spacing, you can determine the direction of the terrain—whether it's going uphill or downhill.
Contour lines forming a circle on a topographic map indicate a hill or summit. This circular pattern of contour lines represents a peak with increasingly lower elevations as you move outward from the center of the circle. This can help in identifying the highest point in a specific area.
Cartographers use contour lines to show the elevation of landforms on maps. These lines connect points of equal elevation, allowing viewers to visualize the shape and steepness of the terrain. The spacing and pattern of contour lines provide valuable information about the topography of an area.
The closer the lines to each other the steeper the slope.
The main topographic map rules include contour lines never crossing, contour lines close together represent steep terrain, contour lines spread out represent flat terrain, and elevation is indicated by the contour lines.
Notice the pattern around that contour line. Then determine the interval that the surrounding contour lines are increasing or decreasing by. Ex. 50 100 150 200, the contour interval would then be 50
The darker contour lines on map are called index contour lines. Numbers that indicate elevations are often written on these lines.
Hachured contour lines are contour lines with ticks pointing downslope that indicate a depression on a topographic map.

Conversely, if contour lines are spaced far apart, it suggests a gentle slope or a downhill area.

Index contour lines are thicker and usually have their elevation labeled. They help users quickly identify key elevations on a topographic map. In contrast, regular contour lines show the shape and elevation of the land but do not have specific labels.

Mountains on a contour map are identified by closely spaced contour lines that form concentric circles around a central point. The contour lines become closer together as they near the summit of the mountain. Additionally, the contour lines may have a "V" or "U" shape that points towards lower elevations, indicating a peak or ridge line.
The contour lines around the mountain would be close together, indicating a steep slope, while the contour lines around the low hills would be more spaced out, indicating a gentler slope.
The difference in elevation between two contour lines that are side by side is the contour interval. The contour interval is the vertical distance between two adjacent contour lines on a topographic map.
The closer the lines to each other the steeper the slope.
The definition of a contour interval is the difference in elevation between two consecutive lines.
