Called both Elevation Lines or Contour Lines
Topographical lines
Elevation contour lines.
Maps can show elevation with contour lines
A topographic map shows equal lines of elevation, in set distances which can vary between maps (dependent on the grade of elevation change). elevation,relief,and slope.
Contour line connect points of equal elevation on a map, whereas relief is the difference in elevation from the highest and lowest on a map.
elevation. the closer the lines the steeper the slope.
Topographical lines
"contour lines"
Contour lines are lines that connect points of equal elevation. A topographical map is a map that uses contour lines to represent the elevation of land surfaces.
Elevation contour lines.
Contour lines show elevation on a topographical map. These lines connect points of equal elevation above sea level, with lines close together representing steep terrain and lines further apart indicating gentler slopes.
Mountains on a map are usually depicted with contour lines or shaded relief to show their elevation and topography. The lines are drawn closer together to represent steep slopes and farther apart for gentler terrain. Peaks are indicated by closed contour lines with the elevation labeled.

Elevation lines and contour lines are just different names for the same thing. Both of them show elevation (or indirectly steepness) on a map.
Contour lines or also known as isohypses, connect points of equal elevation on a map. Contour lines can be curved, straight or a mixture of both. The lines on a map describe the intersection of a real or hypothetical surface with one or more horizontal planes.
The lines connect points that are at the same elevation.
lines of equal elevation are called contour lines.
