contour line
A contour line connects the mountain peak to the valley on the topographic map.
Noun A line on a map or chart that connects points of equal elevation (height) above a specified reference level, such as sea level. Contour lines are used to represent the three-dimensional shape of the land surface on a two-dimensional map.
Contour lines are a fundamental tool in cartography (map-making) and geography. They visually depict the slope, steepness, and form of terrain. The pattern and spacing of the lines indicate the landscape's features: * Closely spaced lines indicate a steep slope or cliff. * Widely spaced lines indicate a gentle slope. * A series of closed loops typically indicates a hill or a depression.
- Noun:
- The contour line for 1000 meters runs along the ridge of the mountain.
- By following the contour lines, hikers can avoid climbing steep hills unnecessarily.
- The map uses brown contour lines to show the shape of the valley.
- Contour interval: The constant difference in elevation between two successive contour lines. For example, if the contour interval is 10 meters, one line represents 100m, the next 110m, and so on.
- Before reading the map, check the legend to find the contour interval.
- Contour (noun): Often used synonymously with "contour line." It can also refer more generally to the outline or shape of something.
- The contour of the coastline is very irregular.
- Contour map (noun): A map that uses contour lines to show relief and topography.
- A contour map is essential for planning this hiking trip.
- Isobar: A line on a map connecting points of equal atmospheric pressure (a related concept in meteorology).
- Isotherm: A line on a map connecting points of equal temperature.
- Isohypse (a technical term used in surveying and meteorology)
- Level curve
- Elevation line
- Topographic map: A detailed, large-scale map that uses contour lines to represent the shape and elevation of the terrain.
- Geologists often work with topographic maps.
- To follow a contour: To travel along a path that maintains a constant elevation, often by following a contour line on a map.
- The trail follows the 200-meter contour around the lake.
